Bill of Materials (Pi Zero)
You need either a Raspberry Pi Zero or a Raspberry Pi Zero W. There is no benefit to having the Pi Zero W. So you might as well get the cheaper Pi Zero, if you can find one in stock.
| Part Description | Supplier | Notes |
|---|---|---|
| Raspberry Pi Zero / Raspberry Pi Zero W | See below | |
| 40 pin 2x20 hat dual male headers | Pi Hut | if not already fitted |
| 1x2 pin straight male 0.1" header | Farnell 1593411 | min order 50 (Not required for c0pperdragon's Amiga board) |
| Micro SD card | PiHut | any size will do |
| Adafruit Mini HDMI Cable | PiHut | |
| Adafruit Serial Cable | PiHut | optional, for diagnostics |
Only the following Pi Models are officially supported but the system will work with any 40pin Pi model:
- Raspberry Pi Zero v1.3 ( PiHut / Pimoroni ) [ without headers ]
- Raspberry Pi Zero W ( PiHut / Pimoroni ) [ without headers ]
- Raspberry Pi Zero WH ( PiHut / Pimoroni ) [ with headers ]
- Raspberry Pi Zero 2W ( PiHut / Pimoroni [ without headers ]
40 Way headers are also available from the above sellers
There is a reset button on the 'hat' which can be used to reset the system but to use this requires some minor changes:
For the Pi zero, zero W or zero WH you must solder a two pin header into the 'run' holes on the zero pcb:
Changes for the Pi zero 2W are more complex as the 'run' holes have been removed:
You will need two right angle pins (one slightly cropped) and a female to female 10cm dupont cable (from ebay) like below:
Note you must use the right angle type on the right, the left one is unsuitable.
This modification can also be used to add reset to other Pi models by soldering a right angle pin into the 'run' hole on those boards
Solder a wire from pin 1 of P4 to pin 39 of P1 on the 'hat':
Solder one of the right angle pins into pin 2 of P4:
Solder the cropped right angle pin to the 'run' pad on the underside of the Pi zero 2W
Connect them together with the dupont cable:
