 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

I was inspired by the new WeAct board so I thought of this. I probably won't build it myself, but if anyone wants the gerbers I'll finish the development off.   The Adafruit DVI breakout board appears to *just* fit between the connectors for the WeAct. I can't verify this as I haven't got a WeAct module. It saves having to solder an HDMI socket though. :) There's nothing on the edges of the module, you could take a bit off each side with a file or something. You get a dim red "standby" LED while it's off and a user-controlled green one while it's on. You can build it in two ways: USB (the default) - Power is supplied via the CP2102 module, which is also the terminal connection. The USB-C on the WeAct is for an external passive USB hub. STND - using standard HDMI firmware. A PS2 keyboard socket is fitted instead of the CP2102 module and power is supplied via the USB-C on the We-Act. There's a proper socket for a WII controller, but the USB version could also use USB controllers. The board is designed to fit the cheap Hammond RM2015 enclosure, like a small CMM2. This is only an idea at present. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

I like it. I will definitely order a set if/when you provide the gerbers. That Adafruit HDMI/DVI module ($1.95 plus shipping) is a brain-saver--as I find all the other little modules to be. ~ Edited 2026-02-25 05:04 by lizby PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on fruitoftheshed |

Can you measure the distance between the sockets on the WeAct if you have one? It would be interesting to see if I've estimated correctly. :) I really need to check that it works out vertically too. It should do. Oh, one other thing, there's no Line Out for audio, only headphones. A resistor (which can be disconnected) mixes some of the left and right channels to form a more central image. I just hope the audio section is quiet enough! The problem is that all the audio modules have the gain far too high by default. In this case we need hardly any gain.

I have 15 tenths of an inch between the outer pins on the rows. That is, I can plug a 16-pin female header across them--1-1/2" pin to pin. PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on fruitoftheshed |

Mick, Was it yourself or Voluout who recommended VGA over HDMI for robustness? My experience with many monitors, many PCs and many cables; if I so much as sneeze, my HDMI signal breaks/makes. Anyone else experiencing this? I really like the VGA of the CMM2; Screw retainers  |
