RADDS2LCD - Adapter to connect standard LCD to RADDS

thingiverse

This is a versatile adapter-PCB that can connect random LCDs with EXT1 and EXT2 (both 10-pin) to RADDS on original SD (10pin) and LCD+ENCODER (12pin) connectors. I designed this PCB using 14-pin cables, as 12-pin cables were not available where I ordered my parts, so the last two pins are left floating on the RADDS-side. If you're using RADDS v1.0 with an 8-pin SD-connector, don't worry - just position the plug's first two contacts in mid-air (marked with a red marker). I've tested this adapter with a "RepRapDiscount Full Graphics Smart Controller" and LCD, Encoder, as well as an SD-card, and everything works perfectly. Here are some useful links: * What is RADDS? * Creator of RADDS * RADDS documentation Enjoy building your own RADDS! This adapter-PCB is designed to be compact, measuring just 5x5cm. It features two separate adapters: one named "...o" and the other "...u". Both can be used with four cables or with two cables and two 8-pin female headers on the back of the PCB (as shown in the photo). The connectors are positioned differently to allow for mounting options - you can choose to mount them up or down from the LCD's back. In my case, I had to mount the connectors upwards, as it was not possible otherwise. Here's what I've uploaded: * Radds2LCDV3-gerbers.zip: Gerber files * Radds2LCD V3.zip: KiCad project * Pictures: + One "RADDS2LCD.u V1" with four connectors + One "RADDS2LCD.o V1" with two connectors and female headers on the back of the PCB Thanks to Claude, there's now a step model available for V1, which includes all four possible variants. Text files: * Configuration to add in "Repetier Firmware" * Configuration to add in "Repetier Firmware Dev Version" (experimental - tested with 1.0.0 and 1.0.1 versions) Important note: Don't use excessively long cables! I used 30cm, but it ended up causing display issues. Thankfully, V3 has three resistors added to prevent level shifter oscillation on the Radds board. When plugging in the connectors, make sure the red marked conductor (pin nr. 1) is facing the correct direction - towards the MOS-FETs and screw terminals on the RADDS-side. I take no responsibility for any damage caused by incorrect usage of this PCB adapter. If you're interested in purchasing a PCB, I'm currently out of stock...
