A-Star 32U4 Prime SV 5 V regulator

For some nifty ideas on what to do with your solar panels

but some of the LPS22DF configuration registers are different

On Rev2 or later boards : there is a resistor that pulling the 8U2/16U2 HWB line to ground

Adafruit Si5351A Clock Generator with STEMMA QT - 8KHz to 160MHz POL_3pi+ 2040 Robot A-Star 32U4 Prime SV 5Never hunt around for another crystal again, with the Si5351A clock generator breakout from Adafruit! This chip has a precision 25MHz crystal reference and internal PLL and dividers so it can generate just about any frequency, from <8KHz up to 150+ MHz. The Si5351A clock generator is an I2C controller clock generator. It uses the onboard precision clock to drive multiple PLL's and clock dividers using I2C instructions. By setting up the PLL and
