ESP32: Difference between revisions

* 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 [https://www.digikey.com/en/products/detail/infineon-technologies/IRLZ44NPBF/ IRLZ44N].

* 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).

There is a three part nomenclature (taken from the [https://products.espressif.com/#/product-selector 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.

Consider the [https://www.espressif.com/en/products/socs/esp32-c6 ESP32-C6] family of SoCs ([[https://www.espressif.com/sites/default/files/documentation/esp32-c6_datasheet_en.pdf datasheet]). Each includes a unicore RISC-V running at up to 160 MHz. They are available in QFN40 and QFN32 SMD packaging. The QFN40 package (the true ESP32-C6) has no onboard flash. The ESP32-C6FH<i>x</i> and ESP32-C6FN<i>x</i> in QFN32 packaging sport <i>x</i> MB of flash, supporting High and Normal temperatures, respectively. SoCs consist of the CPU, RAM, EEPROM—all of the ICs necessary for the ESP32-C6 feature set. The F[HN]x SoCs lack GPIO10, GPIO11, GPIO14, SPICS0, SPIQ, SPIWP, VDD_SPI, and SPIHD, but gain SDIO_CLK and SDIO_CMD, for 30 vs 24 exposed pins.
