A series of 32-bit microcontroller units from Espressif, the successor to their ESP8266.

There is a three part nomenclature (taken from the Product Selector: the SoC, the module, and the devkit. The SoC is the lowest-level component; it contains the processor(s), radio(s), SRAM, and possibly flash+PSRAM. A module adds several elements to the SoC (perhaps most importantly, an FCC-approved RF stack), but will still require some circuit design to use. A devkit bundles a module onto a PCB along with other components (perhaps most importantly, a USB interface), and can generally be used by itself.

Annoyances

  • There are plenty of SMT MOSFETs that will work with the ESP32, but the only through-hole MOSFET I've found that works a damn off its 3.3V output is the (pricey!) Infineon IRLZ44N.
  • The ADC is known to be nonlinear and generally not great.
  • Devkits with an onboard RGB LED often need a bridge soldered between two points on the board before the LED will function (possibly to avoid accidental eye damage; it's pretty bright).

ESP32-S3

The ESP32-S3 is a fantastic little update to the classic ESP32. Some notes:

  • Powering via 5V USB is recommended.
  • Voltage on GPIO47 and GPIO48 is only 1.8 (VSPI), unlike the other pins (3.3, VDD).
  • There are no default I2C pins. All GPIOs can be used with either of the two controllers with no penalty.
  • Some devkits require the two RGB pads to be shorted before their WS2812 RGB LED can be used
    • I suspect this is because the WS2812 can damage the eyes if looked at directly? Unsure.
    • Version 1.0 of the DevKitC had the WS2812 on IO48; Version 1.1 has it on IO38.
