Firmware development for the 36-pin ESP32-WROOM-32 development board — the original DOIT ESP32 DevKit V1 with 18 pins per side, i.e. the 30-pin layout plus the six in-package flash pins (SD0 SD1 SD2 SD3 CMD CLK = GPIO6-11) broken out at the USB end, CH340G or CP2102 bridge, AMS1117 LDO, user LED on GPIO2, GPIO0 not on the header. Use when working on a 36-pin ESP32 devkit (ESP32-D0WDQ6 / ESP32-D0WD-V3, ESP-WROOM-32 module), or when identifying which ESP32 board size you have: project setup…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# ESP32-WROOM-32 devkit — 36-pin

The original DOIT ESP32 DevKit V1, before the flash pins were dropped to make the shorter
30-pin board everyone sells now. Eighteen pins a side: the 30-pin layout plus six pins at
the USB end that go straight to the module's internal flash die.

Those six are the only functional difference from the 30-pin board, and they are a
liability rather than a feature. Everything else — the usable GPIO set, the strapping
pins, the analog budget — is identical.

- `reference/board-hardware.md` — the board: header pin map with every pin's alternate
  functions, the six flash pins, a 20-second procedure to confirm which board size you
  actually have, the USB bridge and auto-reset circuit, power tree, flash partitions —
  **plus** a development guide (§10 toolchain, §11 sdkconfig, §12 flashing and recovery,
  §13 peripheral cookbook, §14 symptom → cause → fix table).
- `reference/esp32-soc.md` — the silicon: pins that do not exist, strapping semantics and
  the `GPIO_STRAP_REG` bit order, ADC/DAC/touch maps and accuracy, IO_MUX vs GPIO Matrix
  and the SPI speed rule, power modes, memory map, deep-sleep wake pins.

How to install

The exact contents, by fingerprint
mdr add alexex1993/mcu-skills/esp32-wroom-36pin@sha256:b45b79f8f53b1faa

The line at the top of this page pins the label git:20261030.816967f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
