Press AND HOLD the button labelled BOOT or 0 (ZERO), then press the RESET button, then release the BOOT button, and it should appear as a serial device. This is common to the ESP32-S2, it's not just this board. **Q: What is the board definition that you're supposed to use for this board in the arduino ide?** A: I use "ESP32S2 Native USB" from the latest (1.8) version of Arduino and the latest (2.0.4) ESP32 board manager. One must press RESET while holding down 0 (ZERO) to connect before upload and then must manually press reset after uploading. You must change the serial port selection between programming and using the serial console because the names change. **Q: Are they designed for wifi? when i activate it on my the chip freezes. on other esp32 s2 the code work without problem** A: They are designed for wifi. 2.4ghz u have to make sure u have the right driver for the USB port. If ur using windows open devices in setting and see if your USB port recognizes the board **Q: Is there a datasheet anywhere for this? The HiLetgo doesn't seem to have one.** A: Just do a search for ESP32-S2-MINI-1 ESP32-S2-MINI-1U Datasheet ## Frequently Bought Together - HiLetgo 3pcs ESP32 S2 Mini WiFi Board Based ESP32-S2FN4R2 ESP32-S2 4MB Flash Type-C Connect - ESP-WROOM-32 ESP32 ESP-32S Development Board 2.4GHz Dual-Mode WiFi + Bluetooth Dual Cores Microcontroller Processor Integrated with Antenna RF AMP Filter AP STA Compatible with Arduino IDE (3PCS) - HiLetgo 3pcs ESP32 Mini ESP-32 Development Board WLAN WiFi Bluetooth IoT Development Board --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.nz/products/450843714-3pcs-esp32-s2-mini-wifi-board-based-esp32-s2fn4r2-esp32](https://www.desertcart.nz/products/450843714-3pcs-esp32-s2-mini-wifi-board-based-esp32-s2fn4r2-esp32) --- *Product available on Desertcart New Zealand* *Store origin: NZ* *Last updated: 2026-04-25*
