The Justification
The Arduino Single power control unit was created for controlling a relay that is able to turn on/off the devices that it powers like the Yocto DUTs. Such need has arisen due to a clean power-off is not always reliable.
The software part
It is required devauto module 'simplepwsc' to control this single power unit. Upon the source directory of this module can be found gen_ard_101.ino to flash the arduino 101
The hardware part
The arduino 101
The circuit
In order to build a power cutter using a relay module, one must follow the circuit provided.
the required hardware
- 1 BJT transistor 2N2222A
- 1 3.3 kOhms resistor
- 1 1N4007 diode
- 1 relay module (RAS-0510)
- 1 Protoboard or perforated PCB (min 4.5x4.5 cm)
- 1 Two positions terminal block
- 1 male outlet connector and 1 female outlet plug
- 14AWG Wire (as needed)
