# Flashen

Voor het flashen heeft u een USB - TTL adapter nodig. Op J2 (onderkant) zitten de aansluitingen voor deze interface. De pinout van de v3.5 hardware is hieronder te zien![](/files/JwqCyjA2p98x71BjySBc)

1. RX
2. TX
3. Flash = GND
4. 3.3Volt
5. GND
6. Reset = GND

Door de **Flash op GND** te houden en **kortstondig Reset tegen GND** aan te houden zal de dongle in download modus komen.
