Charger mods and Pi Zero W HotSpot modifcation

Post by IK8JHL » Sun Feb 09, 2020 5:03 pm

I made my HS OpenGD77 by modifying the charging base to be able to insert the PiZero W directly inside it. To do this I had to replace the original charging circuit with a TP5100, add an LM2596 module to stabilize the voltage at 5V to power the Pi0, change a USB cable. Obviously or replace the original power supply with a 2A one.

Very nice! But watch for temperature, even Pi 0 runs very hot when in closed plastic case.
