Just fried my raspberry pi zero. I used it in conjunction with a Picon Zero – Intelligent Robotic Controller for Raspberry Pi.
Before you continue: The chance I messed up is very high, I don't blame picon or pi, both are excellent tools and I just want to get them to work.
I followed faithfully the desciptions from picon zero website including software installation and hardware setup. There was no point in time, where I actually was using the picon zero. This was the first setup. I don't know yet if the picon zero ever worked and if so, still works... I have one spare pi zero, but don't want to risk it before I know, what actually went wrong. Can you help?
Here a few details:
OS: jessie lite (updated), worked just fine over a month
SD Card: plugged it after the incident into another pi zero and it works just fine
Power supply pi 0: 5V adapter, same as I used over the last weeks
Picon zero setup
- Picon zero set to external power supply:
- motor power jumper set to VIN
- 5V jumper set to RPI (not relevant according to picon zero papers)
- external power supplied by LEGO® Power Functions AAA Batteriebox (88000) with 6x1.2V AAA batteries)
- Lego Batteriebox outgoing line 1 (?V/+) connects to VIN, and GND/0V/-
connects to GND
Motor setup on picon zero
motor A) pins: LEGO® Power Functions M-Motor (8883) No other pins are connected.
Raspberry pi zero state now
no green LED, Wifi dongle doesn't light up, no network connection. I assume it's bricked. Edit: Yes, it is definitely bricked. A Raspberry Pi Zero doesn't come with a polyfuse, so there is no overnight healing to be expected and in my case it didn't happen either. I connected it to a power supply two days later and it didn't sprang to life just got very hot. I am using it as "wearable" now, sort of ;-)
