Crowded Wi-Fi pushing you out? FGRFMesh is an open 868 MHz mesh platform for ESP32 and STM32 that makes sub-GHz networking refreshingly hackable.
Espressif's new dual-core RISC-V ESP32-S31 lands with two dev kits: the networking-focused CoreBoard and a camera-and-LCD Korvo board for HMI builds.
M5Stack's $45 StopWatch Dev Kit squeezes an ESP32-S3R8, AMOLED touchscreen, 6-axis IMU, RTC, mic and speaker into a pocketwatch-sized maker board.
M5Stack's PaperColor packs a 4-inch color E Ink Spectra 6 panel, ESP32-S3, microphone, speaker, RTC, and environmental sensors into one $75 dev kit.
From AMOLED touchscreens to Ethernet jacks, six standout RP2350 boards push the Raspberry Pi Pico 2 chip into wearables, robotics, and IoT builds.
Meet ROBO CORE+, an Arduino UNO-compatible board packing onboard Wi-Fi, a 12-bit DAC, and a browser-based oscilloscope you can run right from your laptop.
Add LoRa long-range radio and GNSS positioning to M5Stack's pocket-sized Cardputer for $48 — a handy tracker, off-grid messenger, and field tool.
Turn a Seeed XIAO ESP32-S3 Sense into a $30 first-person-view RC car with onboard camera, Wi-Fi streaming, and a fully 3D-printable chassis.
Seeed's ESP-FLY is a $60 hackable mini drone powered by the XIAO ESP32-S3 — fully programmable, repair-friendly, and small enough to fly indoors.
Quick take: Kung first microcontroller mo, start with Arduino. If you need Wi-Fi/BLE + more power, go ESP32. For full Linux apps (camera, AI,…
