# Connexions
|
||||
|
||||
Ce document a pour but de recenser les connexions entre les différents composants du robot.
|
||||
|
||||
## Liste des composants
|
||||
|
||||
- Raspberry Pi 3 (RPi)
|
||||
- Arduino Mega 2560 (Ard)
|
||||
- Micronova Mercury FPGA (FPGA)
|
||||
- HEDM-550X Encodeur moteur gauche
|
||||
- HEDM-550X Encodeur moteur droit
|
||||
|
||||
## Connexions de puissance
