SparkFun Thing Plus – ESP32-C5 board offers dual-band WiFi 6, Adafruit Feather pinout, LiPo battery support

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

https://fed.brid.gy/r/https://www.cnx-software.com/2026/03/26/ruview-project-leverages-esp32-nodes-for-presence-detection-pose-estimation-and-breathing-heart-rate-monitoring/

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

ESP-IDF v6.0 framework adds support for ESP32-C5 and ESP32-C61, preview for ESP32-H21 and ESP32-H4

Espressif Systems released the ESP-IDF v6.0 framework a few days ago with stable support for ESP32-C5 and ESP32-C61 SoCs, as well as preview support for ESP32-H21 and ESP32-H4 low-power wireless microcontrollers. The framework also implements a new ESP-IDF Installation Manager (EIM) to make the ESP-IDF installation easier, relies on the low-footprint Picolibc C library, adds security and tooling updates, as well as a few Wi-Fi enhancements, and the ability to update the bootloader over the air. Here are some of the ESP-IDF v6.0 highlights: ESP-IDF Installation Manager - Unified cross-platform tool to simplify the setup process for ESP-IDF and compatible IDEs. It's available as a graphical interface or a CLI for automation and CI/CD pipelines. You can check the installation instructions for your OS. Picolibc replaces Newlib for a smaller memory footprint and better performance on resource-constrained devices. Check the Newlib vs Picolibc comparison for details. Contrary to some of

I spent several days working on a project, only to discover that it can't work due to stuff out of my control...

#espressif should be a bit more careful with their data sheets. 😭

But I do have a PIO mode IDE host for the ESP32-P4, so that's something I guess. 😅 But UDMA is out of the question due to how the PARLIO peripheral doesn't really work as advertised.
