ESP32-S2-Saola-1 Development Board is Now Available for $8

Espressif ESP32-S2 WiFi SoC mass production started at the end of February 2020,  and soon enough we started to find ESP32-S2 SoC and modules for $1 to $2 on sites like Digikey, but so far we had not seen ESP32-S2 development boards for sale.

The good news is the breadboard-friendly ESP32-S2-Saola-1 development board has started to show up for $8 on resellers such as Mouser and Digikey albeit with a lead time of 8 to 12 weeks.

ESP32 S2 development boardESP32-S2-Saola-1 specifications:

  • Supported modules – ESP32-S2-WROOM(-I) & ESP32-S2-WROVER(-I) with 4 MB SPI flash and for ESP32-S2-WROVER modules only, 2 MB PSRAM
  • USB – 1x Micro USB port for power and programming / debugging via USB-to-UART bridge
  • Expansion – 2x 20-pin I/O headers with SPI, I2S, UART, I2C, touch sensors, PWM, etc…
  • Misc – Boot and reset buttons, RGB LED, 3.3V power on LED
  • Power Supply (3 methods)
    • 5V via Micro USB port (default)

ESP32-S2-Saola-1 Board

Espressif ESP32-S2 supports ESP-IDF master or version v4.2 and higher. You’ll find information to get started with ESP32-S2-Saola-1 board and hardware documentation (e.g. schematics) in Espressif’s Documentation website.

I’d expect the price to come down closer to $5 over time, and eventually, many third-party boards will be offered on Chinese resellers like Banggood or Aliexpress. If you want to make use of ESP32-S2 LCD and camera interfaces, it might be good to wait a little longer for the launch of ESP32-S2-Kaluga-1 “Multimedia” development board.

Somewhat tangental to the discussion, but do we know why Espressif has chosen so many different sizes of PSRAM for their modules?

I’m really curious how this being a single core part is going to effect code written for the dual core ESP32s. Having one core that handled the wifi/hardware and another completely free to run the application was pretty nice.

Also, there seems to be no Bluetooth on the newer S2. Maybe @Jean can comment if he has updated information.
