If you’re into small MCU boards with an integrated display, you’re in luck as LOLIN launched the S2 Pico board with ESP32-S2 and an OLED display about at the time same as LILYGO T-Display RP2040 board we covered yesterday.
Wemos/LOLIN S2 Pico board offers WiFi connectivity, a 128×32 OLED display, USB Type-C port for power and programming, as well as the usual GPIO headers in a compact 50×23 mm form factor.
- SoC – Espressif Systems ESP32-S2FN4R2 single-core Xtensa LX7 processor with 4MB flash, 2MB PSRAM, and WIFI connectivity only, i.e.no Bluetooth support
- Display – 128×32 OLED display based on SSD1306 driver
- USB – USB Type-C port for power and programming
- 16-pin + 8-pin headers with 21x GPIO with interrupt/PWM support, ADC, DAC, I2C, SPI, UART, USB OTG
- 4-pin I2C connector
- Misc – Reset and user buttons
- Power Supply – 5V via USB-C port
- Dimensions – 50 x 23 mm
Just like Wemos/LOLIN S2 Mini board, also based on ESP32-S2, and launched last month, the S2 Pico supports MicroPython, Arduino, and the ESP-IDF. MicroPython is the default firmware, but considering the Arduino Core for ESP32 v2..0.0 was released just about two weeks ago with support for ESP32-S2, it should be just as stable as the MicroPython firmware. You’ll find more details on the Wiki including very basic instructions to get started with MicroPython and Arduino on the board.
LOLIN S2 Pico is sold for $6.90 plus shipping, or $2.9 more than Wemos S2 Mini ESP32-S2 board without the OLED display and a much tinier form factor.
