TTGO ESP32-S2 WiFi IoT Board Comes with Optional MicroSD Card and Battery Support

TTGO ESP32-S2 ESP32-S

All ESP32-S2 boards I’ve seen so far were from Espressif Systems themselves including ESP32-S2-Saola-1 and ESP32-S2-Kaluga-1, but LilyGO TTGO ESP32-S2 is the first third-party board for sale so far. The tiny board is somewhat similar to ESP32-S2-Saola-1 board and comes in two versions with a similar form factor, but a completely different pinout and the presence of a MicroSD card socket and a battery connector on one of the boards. The simpler board is called “ESP32-S2 ESP32-S-WOOR” and comes with ESP32-S2-WROOM module, while the one with more features is named “TTGO ESP32-S2 ESP32-S ” and features its own circuitry built around ESP32-S2 WiSoC. Both TTGO ESP32-S2 boards share many of the same specifications: SoC – Espressif Systems ESP32-S2 single-core 32-bit Tensilica LX7 processor with 320 kB SRAM, 128 kB ROM, System Memory – 8MB PSRAM Storage – 4MB flash; XY-ESP32-S only: MicroSD card socket Connectivity 2.4GHz 802.11b/g/n WiFi 4 connectivity […]
