I’m working on a synthesizer based on the Teensy Micromod. I’m coming from Teensy 4.0, so I’m trying to wrap my head around some differences. I’ve found the right M2 socket and SMT standoff (thanks to this forum).
In order to make the Micromod “work” I think I’ll need to borrow some things from the Micromod ATP carrier board. Specifically the following parts of the schematic:
Voltage Regulation (to power the Micromod Teensy)
USB (to power and program the device)
Buttons (for Boot and possibly Reset/power)
I do not plan to implement USB Host. I do plan to use Analog 8 Input, which is used for voltage testing on the ATP board.
Am I on the right track here (implementing the above items from the Sparkfun schematic)? Am I missing anything vital in the Micromod ecosystem?
For what it is worth, when the Teensy Micromod was in beta or maybe maybe just after it released, I did my own board for the Micromod… (Only board I have done that I had it partially assembled due to how small pads are…)
But it is probably overkill for your needs, but things you might consider…
I have socket that allows me to plug in T4 size things, in particular I can plug Audio board into it.
All of the IOPins - with Teensy pin numbers shown…
SDCard - it is setup with SDIO.
USBHost - you already mentioned you don’t need
Display Connections:
One is setup with the pinout of the ILI9341 that PJRC now Sparkfun sells? It also works for ILI9488 and ST7796 displays
The other has the Adadruit display breakout, that I have used for ST7789/ST7735…
This has been my goto board for Teensy stuff for several years.
However not that long ago I was playing with Micromod with different cameras, and did a quick and dirty plugs into the ATP, which again has SDIO, Camera and the displays…
I’m adapting an earlier design using the standard Teensy 4.0 to the Micromod. I think I need to add in things I listed above to make it work as my Teensy 4.0 did.
I’ll be ordering a round of prototypes soon - finders crossed.
