AI Overview
“esp” is most commonly shorthand for Espressif Wi‑Fi/BLE microcontrollers (ESP32/ESP8266). Here are the most relevant picks by use-case:
ESP32 dev boards (Wi‑Fi + Bluetooth LE)
- For a modern, broadly compatible starter board: ESP32-C3 RISC V Developer Board - 4 MB SPI Flash (ESP32‑C3, 4MB flash) ($23.48)
- For newer connectivity (adds Wi‑Fi 6 + Zigbee/Thread support): ESP32-C6-DevKitC-1-N8 - 8MB SPI Flash (ESP32‑C6, 8MB flash) ($24.10)
- If you want lots of memory for larger projects (UI, audio, buffering): ESP32-S3-DevKitC-1-N8R8 - ESP32-S3-WROOM-1 (ESP32‑S3, 8MB flash + 8MB PSRAM) ($46.60) or ESP32-S3-DevKitC-1-N8 - ESP32-S3-WROOM-1 Dev Board - 8MB Flash (8MB flash) ($37.58)
- Feather-format (battery-friendly ecosystem, headers included): Adafruit ESP32 Feather V2 with Headers - 8MB Flash + 2 MB PSRAM (8MB flash + 2MB PSRAM) ($35.43)
- Pro Mini footprint + Qwiic/I2C: SparkFun ESP32 Qwiic Pro Mini (ESP32‑PICO‑MINI, includes PSRAM) ($23.04)
ESP8266 modules & quick Wi‑Fi add-ons (Wi‑Fi only)
- SMT Wi‑Fi module for embedded builds: ESP8266 SMT Module [ESP-12S] (ESP8266, compact module) ($13.38) or ESP8266 SMT Module - ESP-12 ($18.48)
- Simple on/off switching project (pairs with ESP‑01/ESP‑01S): ESP8266 ESP-01/ESP-01S Relay WiFi Smart Control Module for Arduino (relay carrier controlled via GPIO0) ($4.29)
Thread/Zigbee border router (Matter/Thread networking)
- Bridge Thread mesh ↔ IP network: Espressif Border Router - ESP Thread BR-Zigbee GW ($26.18)
- Add Ethernet to the border router setup: Espressif Ethernet - ESP Thread BR-Zigbee GW_SUB ($45.82)
ESP32 display/terminal devices (ESP-powered UI)
- Handheld ESP32-S3 terminal w/ 3.5" 480×320 capacitive touch + OV2640 camera: ESP Terminal- 3.5 inch 480x320 SPI TFT capacitive touch display with OV2640 camera ($87.57)
- Larger HMI-style touch display w/ case: CrowPanel 5.0"-HMI ESP32 Display 800x480 RGB TFT LCD Touch Screen with Case (5.0" 800×480, ESP32‑S3 based) ($69.22)
