When people say “ESP32 vs STM32”, they’re really comparing a Wi-Fi SoC (ESP32) with a huge family of general-purpose microcontrollers (STM32). They overlap, but they’re not aimed at the same sweet spot. If you’re starting a new embedded project today,…
Both ESP32-S2 and ESP32-S3 are “second-wave” ESP32 chips: they add native USB and more modern security features compared to the original ESP32. But they target slightly different use cases: If you’re deciding what to base a new board or project…
Espressif’s ESP32 family has exploded with variants, but for most makers and IoT projects the real question is simple: Should I use the classic ESP32, or the newer ESP32-S3? Both chips are dual-core Wi-Fi + Bluetooth SoCs, both are cheap,…
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…
(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.…
