ESP32

From dankwiki

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).

SoCs, modules, devkits

Consider the esp32-C6, a unicore RISC-V running at up to 160 MHz. At the core is the "ultra low-power SoC", the ESP32-C6, available in QFN40 and QFN32 5x5mm SMD packaging. The QFN40 package has no onboard flash. The ESP32-C6FHx and ESP32-C6FNx in QFN32 packaging sport x MB of flash, supporting High and Normal temperatures, respectively. One of these lies at the heart of every "ESP32-C6" product:

The F[HN]x models lack GPIO10, GPIO11, GPIO14, SPICS0, SPIQ, SPIWP, VDD_SPI, and SPIHD, but gain SDIO_CLK and SDIO_CMD, for 30 vs 24 exposed pins.

This is the SoC. To run properly or even boot, you need put a decent amount of circuitry around it, including a crystal oscillator. Adding the basics results in a module, such as the ESP32-C6-MINI (suffixed with -1 for an onboard antenna, or -1U with a U.fl antenna hookup). There are six ESP32-C6-MINI modules: -1 and -1U are both offered around the ESP32-C6-FN4, ESP32-C6-FH4, and ESP32-C6-FH8. All six have the same pinout, in a QFN32 package making available 15 GPIOs:

The ESP32-C6-MINI-1 and -1U have the same pinout.

Relative to the SoC, the module includes the antenna circuit, the 40 MHz crystal oscillator, and some of the power circuitry. To see the detailed differences, look at the schematic in the ESP32-C6-MINI datasheet. To get this booting, you need ground the necessary pads, hook up and drive 3V3 and EN, and bootstrap IO8 and IO9 based on whether you want to boot into the bootloader or application code (which will need to be written to the flash). Note that this is an SMD device, with many small pads. Using it pretty much requires manufacturing a PCB and mounting the module, a nontrivial task. If you're stuck with a breadboard, you can use a QFN32 breakout, but this doesn't eliminate the need to solder all those pads (you can also get a "programmer" which will hold the chip in its socket, but they're like $25 minimum).

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.
