I2C controllable buck-boost converter (2Layer version)
WARNING! The 2 layer version pcb has not been tested in live
The 2 layer version has lower cost.
This is a buck-boost converter based on the TPS55289. This converter is I2C controllable, which means you can control it's output voltage with any arduino, any esp32, stm32 etc...any MCU.
INPUT VOLTAGE: 3V-30V
OUTPUT VOLTAGE (no load): 0.9V-21.4V in 10mV steps OR
OUTPUT VOLTAGE (no load): 0.9V-10V in 5mV steps
Dimensions(WxLxH): 31.7x54.6x16.5(mm), 1.25*2.15*0.65(in)
Order instruction: 2 layer, 4mil track spacing, 0.25mm+ min hole size
For more info on how to control the board see the video on YT:
