Power management for 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/

SuperCap UPS – Backup power supply for Raspberry Pi / ESP32 IIoT devices

The new 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.

As an addition to Industrial IoT family of TECHBASE’s products, such as ModBerry (Raspberry Pi Compute Module 3 powered) industrial gateways and Moduino (ESP32 powered) end-point devices, the SuperCap UPS-SC01 serves well as an additional, highly efficient and fanless power source to allow continuous operation of connected devices in difficult conditions, such as extended industrial temperature range. Perfect solution for a multi-range applications, especially for embedded IIoT / Industry 4.0 systems, where stability and high availability is most important.

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.
