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: … Continue reading
I made a little board for a SHT21 humidity and temperature sensor from Sensirion. There are several versions with I2C interface, PWM output and SMD/analog interface. I’ve got the one with Sigma Delta Modulation (SMD) output, is a bit-stream of pulses; the … Continue reading
I have a few MSP430G2955 around but non of my Launchpads are capable of programming this MCU. Texas Instruments released a while back all the informtation needed to build the new ez-FET lite. The eZ-FET lite is a low cost USB-based … Continue reading
