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/
