Tom from Magic Smoke writes: This is my first time designing a PCB for MSP430. I really like the NRF24L01+ booster pack but I would like something smaller to use for remote temperature sensors. With that in mind I’ve designed a 24.5 x 50 mm PCB (2 on a 5×5 cm prototype) featuring MSP430G2553 and […]

Juan Ignacio has designed a INA219 current sensor DIY Breakout board: Another small board, this time for a INA219. The INA219 is a high-side current shunt and power monitor with an I2C interface. For testing I used Rei VILO library with a MSP430G2553 and Energia, and I measured the power consumption for this simple circuit. […]
