SparkFun Thing Plus – ESP32-C5 board offers dual-band WiFi 6, Adafruit Feather pinout, LiPo battery support
Espressif has recently released the ESP-IDF v6.0 framework with support for ESP32-C5 and ESP32-C61, so we can expect more ESP32-C5 boards. Following the launch of boards like DFRobot FireBeetle 2 and the Espressif DevKitC-1, SparkFun has now launched its Thing Plus - ESP32-C5, an Adafruit Feather-compatible board based on the ESP32-C5. The timing is no coincidence. Although the ESP32-C5 dual-band WiFi 6 SoC was announced back in 2022, hardware makers have been waiting for stable software support. With the release of ESP-IDF v6.0, the ESP32-C5 moves from “preview” to “stable” and adds key features, such as Safe Bootloader OTA updates. This enables the ROM bootloader to fall back to a recovery partition if an update fails, making it reliable enough for companies like SparkFun to launch hardware for remote deployments and Matter-compatible smart home applications.

RuView project leverages ESP32 nodes for WiFi-based presence detection, pose estimation, and breathing/heart rate monitoring
RuView is an open-source "WiFi DensePose" implementation leveraging multiple ESP32 nodes to turn WiFi signals into real-time human pose estimation, vital sign monitoring, and presence detection without relying on video cameras. WiFi DensePose is a sensing technique, first explored in academic research, that leverages WiFi signals to reconstruct human pose. RuView implements this technique in Rust or Python, and relies on your WiFi router and several ESP32 nodes to track body pose, detect breathing rate, and measure heart rate even through walls. As we'll discuss below, this project has its own controversy, as some claim it's fake. The solution relies on Channel State Information (CSI) disturbances caused by human movement to reconstruct body position, breathing rate, heart rate, and presence in real time using "physics-based signal processing and machine learning". That obviously means you need CSI-capable hardware, and not all consumer WiFi nodes implement it. The project description lists various
