(Safe pins, ADC, I²C, SPI, USB, RGB LED) The ESP32-C6-DevKitC-1 v1.2 is Espressif’s entry-level board for the ESP32-C6-WROOM-1/1U module – a Wi-Fi 6 + BLE 5 + 802.15.4 (Thread/Zigbee) SoC with RISC-V core and 8 MB flash. This guide is…
(LCD, encoder, RGB LED, audio, IR, “safe” pins) The ESP32-C3-LCDkit is a small all-in-one dev board with: It’s perfect for small GUI gadgets, knobs, thermostats, timers – but many GPIOs are already “spoken for” by the LCD and other peripherals.…
(Safe pins, ADC, I²C, SPI, UART, RGB LED) The ESP32-C3-DevKitM-1 is Espressif’s tiny RISC-V dev board based on the ESP32-C3-MINI-1 / MINI-1U module – a very compact Wi-Fi + BLE module with 4 MB flash. It’s designed to plug into…
(Safe pins, ADC, I²C, SPI, UART, LED) The ESP32-C3-DevKitC-02 is Espressif’s small RISC-V dev board based on the ESP32-C3-WROOM-02 module (4 MB flash, Wi-Fi + BLE). Almost all useful GPIOs are broken out on the two headers J1 and J3.…
(Safe Pins, ADC, I²C, SPI – and why there is no touch) ESP32-C2 is the small brother in the ESP32 family: Wi-Fi 4 + BLE 5, RISC-V core at up to 120 MHz, and only 14 GPIOs – the ESP8684…
This project shows how to do a simple LoRa “Hello World” send & receive test using two TTGO LoRa32 (SX1276) boards with built-in 0.96″ SSD1306 OLED displays. We’ll configure one board as a sender, which sends a counter every second,…
The ESP32-S3-DevKitC-1 is Espressif’s entry-level development board for the ESP32-S3-WROOM-1 / 1U / 2 modules – a Wi-Fi + Bluetooth LE SoC with dual-core CPU, vector instructions for AI, and plenty of GPIOs. Espressif Docs This guide focuses on pinout…
The ESP32-S2-DevKitC-1 is Espressif’s entry-level development board for the ESP32-S2 – a single-core Wi-Fi microcontroller with native USB, 43 GPIOs, ADC, DAC, touch, and a rich set of peripherals. This guide focuses on pinout and GPIO selection for the DevKitC-1,…
1. ESP32 DevKit / ESP-WROOM-32 Overview The ESP32-WROOM-32 module exposes up to 32 GPIO pins, plus power, enable and boot configuration pins. These GPIOs are highly multiplexed: the same pin can often be used as digital I/O, ADC, touch, I²C,…
The ESP32 family has grown massively since the original ESP-WROOM-32 module.Today we have dozens of chips, modules, and development boards, each optimized for different use-cases—from Wi-Fi/BLE automation to AI-enabled audio processing and ultra-low-power IoT nodes. This guide provides a complete…
