Pin Mapping
This page will describe how the names of the pins on the PocketBeagle/OSD3358 coorespond to signals on the rest of P1.
P1 consists of 3 PCBs all stacked together through headers. Each board has its own schematic and each header and signal may have different names on each board.
UTH and UTD versions of P1
Caution: Neither PocketBeagle nor Interface board is keyed, so it is possible to plug together incorrectly. Use the above diagram to ensure you are plugging together correctly.
Caution: In the case of UTH version - with enough force, it is possible to plug a 24 pin connector into the 26 pin connector socket. Please don't do that.
P1 boards:
Adapter board (schematic here). This board acts connects PocketBeagle to the M2 interface board, adds a battery connector and full-sized USB A connector.
Interface board (schematic here). This is the same interface board used with M2. This board has all of the automotive interfaces and power supply.
Headers connect throughout P1 as follows:
PocketBeagle Headers | Adapter board headers | Interface board headers |
P1 connects to: | J5 | - |
P2 connects to: | J6 | - |
- | J2 connects to: | J3 |
- | J3 connects to: | J4 |
- | - | J5 (26 pin connector) |
- | - | J1 (UTD) or J2 (UTH) |
