ESP32 based microcontroller module.
- 2 analog inputs (connects to internal ADC by level shifters), -8…+8 V range (-12…+12 acceptable)
- 3 analog outputs (internal PWM with lowpass and buffer), -5…+5 output range
- TRS MIDI-A input jack
- 128×64 OLED screen
- encoder with push button
- secondary push button and reset button
- BT/WiFi capabilities
- more ESP32 GPIO exposed on pads (WARNING! these additional pins is not tolerant to microrack standard signals, use only with 3.3 devices)
Out of the box firmware contains MIDI to CV and 2 channel oscilloscope features.

Hi, sounds really interesting. I understand specs might not be finalised yet, but can you say anything about the module? Like number of I/O, what processing platform you plan to use, will there be an sdk or will it be open to programming?
We plan to make a more detailed description within 2-3 days.

Hey. As far as I understand from the picture, it has 3.5 trs midi input on top. (at least it seems like it)
To my knowing, there are two widely used “standards” - MIDI Type A and Type B.
(https://minimidi.world/)
Thus, two questions
- Is that 3.5 midi input?
- If yes, which of these pinouts is used here?
(Basically that’s important to buy or solder the right cable)
Yes, this is MIDI input. We use type A

What screen resolution is it going to have? I’m trying to understand if it would be feasible to hack it into a sequencer thing by adding a keyboard
We have 128×64 OLED display, HS96L03W2C03
