Sleep mode and power saving for Raspberry Pi based ModBerry devices
Sleep functionality for ModBerry/Raspberry Pi devices
TECHBASE company designed new extension module for RaspberryPi-based devices, ModBerry series for better power management in changing conditions of industrial environments. With the use of GPIO the module can manage sleep mode or safe shutdown of device in terms of unexpected drop in the power network.
In last few years developers marketed wide range of ARM-based development boards, lacking in enhanced power management, especially sleep and wake up modes, commonly used in PC-grade computing. These boards are not adjusted for battery power supply, so it’s natural that sleep/wake functions should be implemented. In connection with the development of solutions based on Linux-SBC, key factor is adding sleep modes to any remote installation
With built-in algorithms and the possibility to program on your own, the TECHBASE’s sleep/wake addon module can wake the device using schedule/timer. Another option is wake on external trigger, e.g. change of input, etc. All the options for sleep, shutdown and wake can be configured for various scenarios to ensure constant operation of devices, safety of data and continuity of work in case of power failure in any installation.
The preliminary module for ModBerry devices is available on request and delivery time will be specified by Sales Dept. depending on the size of the project.
Sleep mode with additional power backup
Additional power management option for ModBerry devices is sleep functionality enhanced with SuperCap UPS energy backup device. This solution allows programming scenarios including the execution of chosen actions, in order to save data, send a notification and restart/shutdown the controller after completion.
Advanced power management solution
Most advanced configuration includes use of Moduino ESP32 device for extra logic for wake up / sleep scripts. This addon will allow the RaspberryPi-based ModBerry device to be woken up by Moduino controller via Wi-Fi/GSM/LAN networks.
Moduino-ModBerry symbiosis allows wide range of wake-up/sleep schedule customization, in order to perform best and save energy accordingly to power supply state. Arduino and MicroPython environments provide libraries to control different scenarios of data and power management.
New SuperCap options for Moduino/ModBerry
The SuperCap UPS-SC01 backup power supply is equipped with a highly available backup feature to safely bridge fluctuations, drops or failures accompanying standard 9~30VDC supply voltage and avoid interruption of output voltage in industrial and automation environments. For this purpose SuperCap UPS-SC01 utilizes two supercapacitors (so-called supercaps) as a durable, cycle-resistant and maintenance-free solution for backup energy storage and failure safety.
The UPS-SC01 model is available for purchase at price set to 90€. SuperCap family offers now preliminary and revised models: UPS-SC02 with twice the capacity at 135€ and UPS-SC04 respectively at 180€ with quadrupled capacity of the base device, which can be preordered at our new Industrial IoT Shop, here: https://iiot-shop.com/product/supercap-ups/

To ensure constant development of TECHBASE’s solutions and cutting-edge technology, the NanoPi platform part of ModBerry series is expanded by updated ModBerry M300 N2 product, based on NanoPi NEO2. The new addition features Quad-core Cortex-A53, twice more RAM than previous version of NanoPi NEO and Gigabit Ethernet for fast communication.
For even wider range of communication interfaces and application possibilities, TECHBASE offers now ModBerry M300 N2+ based on the NanoPi NEO Plus2. M300 N2+ is equipped with 8GB eMMC, features more USB ports, Gigabit Ethernet port like M300 N2 and is supported with onboard Wi-Fi/Blutetooth 4.0 to ensure many channels of data management.
ModBerry M300 series can optionally support an external 2.5″ SATA hard disk and 2242 SSD storage units with M.2 interface thanks to onboard JMS567 USB to SATA controller. With extra storage space, data management of specific installations would be more convenient than sending all unprocessed data into cloud or directly to user.
OrangePi capabilities
To meet the Industrial IoT market demands the ModBerry family joined new embedded computer platform, offering adjustable solutions for every industrial installation. ModBerry M300 O1/O2 series is formed by two OrangePi module boards offering different approach to IoT than NanoPi solutions.
ModBerry M300 O1 based on OrangePi Zero Plus features Allwinner H5 (Quad-core Cortex-A53) SoC, moderate 512MB RAM, storage memory option with microSD slot, USB and Gigabit Ethernet port. The wireless communication is supported with onboard Wi-Fi module.

Symbiosis of RaspberryPi and ESP32 in one device
The latest configuration of ModBerry 500 device presents the important milestone in TECHBASE’s offer. The introduction of two platform symbiosis, RaspberryPi Compute Module 3 assisted with Espressif’s ESP32 module brings new possibilities of application to life. High performance of CM3, if compromised by exposition to harsh environmental conditions or sudden drop of power, is aided with low-powered ESP32’s real-time system to continue operation of the device. ESP32 module can be battery powered, same as standalone Moduino series, based on similar solution.
ESP32 subsystem for ModBerry 500
Main difference between ESP32-aided ModBerry device and ESP32-based Moduino is that the first one benefits from low-power module aid to prevent errors and downtimes. ESP32 compared to Compute Module 3 works much longer on battery power supply and offers extended sleep modes. Real-time system of ESP32 and simplified communication between ESP32-aided ModBerry device and Moduino controllers drastically shortens the time needed for the system implementation and the cost of maintaining the application. It also enables the use of Espressif’s Wi-Fi-based technology in the ESP-NOW and ESP-MESH networks.
The separate ModBerry-Moduino Ecosystem, working as a separate devices is a solution for scattered object and installations monitoring – with the use of wireless communication interfaces (e.g. LoRa, NarrowBand-IoT, ZigBee, Wi-Fi, Bluetooth, etc.), rather than standard wired networks. For more information ask TECHBASE via one of contact form at: https://modberry.techbase.eu/ & http://moduino.techbase.eu/
Coming soon
TECHBASE plans further development of the product, particularly the issue of remote access to input/output resources and use of ESP32 as a Security Chip – hardware layer protection against hacking (very important issue in current IoT business).
ModBerry brings Compute Module 3 to next level of Industrial IoT
Introduced with Moduino series, TECHBASE developed further the project of modular aluminum case for their devices. The latest version of housing allows ModBerry to expand in any dimension, supporting additional extension cards (e.g. I/Os, modems, opto-isolation, accelerometer, etc.) and DIN rail mount, that can be retracted into device itself. TECHBASE constantly improves the project to support different platforms (e.g. Raspberry Pi Compute Module 3, NanoPi, ESP32, UpBoard and probably more in the nearest future) and brings them to Industrial IoT world.
Supercapacitor power support for ModBerry
To improve the possibilities of ModBerry devices, TECHBASE added supercapacitor UPS option for ModBerry 500 configurations. Additional power supply available at emergency situations, such as power drop or loss, allows the device to log the recently acquired data and send the notifications to user regarding the occurred event. The supercap support for ModBerry ensures safe system shutdown and protects memory from fragmenting, so there is no need to use diagnostic tools afterwards.
ModBerry enhanced with OLED screen
Just like ESP32-based Moduino series, the ModBerry computers can be now equipped with OLED 0.96″ 128×64 screen via i2c extension protocol. The is small, only about 1″ diameter, but very readable due to the high contrast of an OLED display. Because the display makes its own light, no backlight is required, therefore reduces the power required to run the OLED.
LORA MQTT: Perfect Couple – in RaspberryPi & ESP32 Ecosystem
TECHBASE Industrial Computers are designed for easy integration of LoRa / MQTT networks. ModBerry devices base on Raspberry Pi / NanoPi / Intel UpBoard platform communicate with both Cloud and Sensor layer (backed with ESP32 Moduino devices) of your installation via MQTT protocol. Gateway utilizes the features of many protocol libraries, such as original TECHBASE’s iMod protocol controller – installable both on the Gateway device itself or externally with wide range of possibilities (industrial computer, hosted server, etc.). Our devices fully support Node-RED, CODESYS, OpenHAB and many more open protocol libraries.
Wide range of protocol support
All TECHBASE’s solution can be empowered with iMod software incl. protocol support for industrial interfaces, e.g. M-Bus, Modbus, SNMP, MQTT. iMod software works seamlessly with Node-RED using MQTT protocol, allowing use of bacnet and direct control over devices I/Os with Google’s platform-neutral protobuf – extensible mechanism for serializing structured data and zeroMQ controls to connect the code in any modern language, on any platform. The protocol drivers library can be expanded with CODESYS development system to support PROFIBUS, CANopen, EtherCAT, PROFINET and EtherNet/IP.
