ESP32-S2 dev. board: ESP32-S2-Saola-1 and nanoESP32-S2

ESP32-S2 is a highly integrated, low-power, single-core Wi-Fi Microcontroller SoC, designed to be secure and cost-effective, with a high performance and a rich set of IO capabilities. They are an ideal choice for a wide variety of application scenarios relating to the Internet of Things (IoT), wearable electronics and smart home. (ref: https://www.espressif.com/en/products/socs/esp32-s2)

Currently, it have 6 modules include:

• ESP32-S2-WROOM & ESP32-S2-WROOM-I (no PSRAM)
• ESP32-S2-WROVER & ESP32-S2-WROVER-I (with PSRAM)
• ESP32-S2-MINI-1 & ESP32-S2-MINI-1U (ESP32-S2FH4)

My boards with ESP32-S2 Module: ESP32-S2-Saola-1 and nanoESP32-S2

My ESP32-S2-Saola-1 (with ESP32-S2-WROVER module):

ESP32-S2-Saola-1 is a small-sized ESP32-S2 based development board produced by Espressif.

It currently support:

- ESP32-S2-WROVER

- ESP32-S2-WROVER-I

- ESP32-S2-WROOM

- ESP32-S2-WROOM-I

WROOM: no PSRAM

WROVER: with PSRAM

-I: IPEX Antenna

without -I: PCB Antenna

My unit have ESP32-S2-WROVER (PCB Antenna, with PSRAM) module.

My nanoESP32-S2 (with ESP32-S2-WROVER-I module):

nanoESP32-S2 is another development board of ESP32-S2 produced by museLab. It support the four modules also, ESP32-S2-WROVER, ESP32-S2-WROVER-I, ESP32-S2-WROOM and ESP32-S2-WROOM-I.

One advantage of this board is it have a extra USB port (marked "esp32"), connect to ESP32-S2 chip directly. It is more easy to develop using CircuitPython.

My unit come with ESP32-S2-WROVER-I module (IPEX Antenna, with PSRAM) module.
