The ESP32-DevKitC V4 is the “classic ESP32” dev board most tutorials assume. But the internet is full of half-truths: pinout posters without context, ADC guides ignoring Wi-Fi conflicts, and “use GPIO0” recipes that break boot. This guide is meant to…
This guide explains the most common ESP8266 variants (ESP-01, ESP-12E/F, NodeMCU and D1 mini) and shows their pinouts, safe GPIOs, and boot-sensitive pins to avoid. The ESP8266 started life as a tiny Wi-Fi module but quickly became a full microcontroller…
This guide compares ESP32 and STM32 to help you choose the right MCU for your project based on connectivity, real-time needs, power use, and tooling. When people say “ESP32 vs STM32”, they’re really comparing a Wi-Fi SoC (ESP32) with a…
If you are choosing between the ESP32-S2 and ESP32-S3 for a new project, the ESP32-S3 is the better default for most users. Both use 240 MHz Xtensa LX7 processors, both support 2.4 GHz Wi-Fi and native USB OTG, and both…
This guide compares ESP32 (original, ESP32-WROOM / WROVER) vs ESP32-S3, and ends with practical “choose this if…” scenarios. Espressif’s ESP32 family has exploded with variants, but for most makers and IoT projects the real question is simple: Should I use…
The ESP32-P4-EYE is one of Espressif’s newest dev kits: a tiny “camera-in-a-box” based on the ESP32-P4 SoC, with a built-in LCD, 2 MP camera, microphone, MicroSD and dual USB-C ports. It’s designed as a ready-made platform for AI vision and…
The ESP32-P4-Function-EV-Board v1.5.2 is Espressif’s flagship multimedia dev kit for the ESP32-P4: On top of that, the board carries an ESP32-C6-MINI-1 module that provides Wi-Fi 6 + Bluetooth LE connectivity. All ESP32-P4 GPIOs that Espressif exposes are routed to a…
(Safe Pins, ADC, I²C, SPI, USB, RGB LED) The ESP32-H2-DevKitM-1 is Espressif’s low-power Bluetooth LE + 802.15.4 (Zigbee/Thread/Matter) dev board based on the ESP32-H2-MINI-1/1U module. It’s basically an “ESP32 without Wi-Fi” but with full BLE + Zigbee/Matter support and 4…
This guide explains the ESP32-C6 DevKitC-1 v1.2 pinout, showing which GPIOs are safe ,which affect boot or native USB and how to pick pins for ADC, I²C, SPI, UART, and the RGB LED. The ESP32-C6-DevKitC-1 v1.2 is Espressif’s entry-level board…
(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.…
