PiCoBo is a multi-target board. I designed it using the MSP430G2553 (20/28 pin version), which is part of the MSP430 Texas Instruments family of ultra-low-power microcontrollers.
The board includes also a CP2102 which can be used for communication over UART.
The board can be supplied using a C2032 battery, over USB or external DC source up to 10V. It uses a TPS77301DGK to regulate the max. voltage of 3.6V needed for the MSP430.
Up to three IRLL2705 can be soldered to the board to switch on/off directly (or using PWM) voltages up to 55V and 3.8A. Additionall multiple pinouts are available to connect external sensors (e.g. DHT11), servo motors, leds etc. For testing uses it can be programmed using the MSP430G2553 LaunchPad.
