Fix an ESP32-S3 that is not detected over USB. Covers native USB vs USB-UART, BOOT/RESET recovery, ROM download mode, Arduino USB CDC settings, GPIO19/20 conflicts, drivers, cables and boot loops.
XIAO ESP32-C6 pinout with D0–D10 GPIO mapping, I2C, SPI, UART, USB, battery charging and ESPHome setup. Includes the key pins to avoid.
ESP32-S3 N8R8 vs N16R8: both have 8 MB PSRAM; N8R8 has 8 MB flash and N16R8 has 16 MB. Includes correct QIO/OPI Arduino and PlatformIO settings.
Quick Summary (TL;DR):ESP RainMaker Neo, announced by Espressif on 5 August 2026, is an open-source device-to-cloud-to-phone IoT platform for ESP32 products. It is much more than an ESP32 library: the Neo stack includes the device firmware SDK, AWS serverless cloud…
Quick Summary (TL;DR):The ESP32-H2, ESP32-H21 and ESP32-H4 are all low-power Espressif chips built around Bluetooth LE + IEEE 802.15.4 rather than Wi-Fi. The H2 is still the safest choice today for mature boards, Arduino support and proven Thread/Zigbee development. The…
ESP32-S31 Korvo-1 vs Function-CoreBoard-1 compared: choose Function-CoreBoard-1 for GPIO, Ethernet and USB development; Korvo-1 for voice, audio, camera and HMI.
Quick Summary (TL;DR):The ESP32-S31 and ESP32-P4 overlap in HMI, AI, display and camera projects, but they are not really the same class of chip. The S31 is a high-performance connected MCU: dual-core RISC-V up to 320 MHz, 2.4 GHz Wi-Fi…
