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.

AngstromIO – A tiny 9.0 x 8.9 mm ATtiny1616 board that fits on top of a USB-C connector

https://fed.brid.gy/r/https://www.cnx-software.com/2026/03/26/angstromio-a-tiny-9-0-x-8-9-mm-attiny1616-board-that-fits-on-top-of-a-usb-c-connector/

AngstromIO – A tiny 9.0 x 8.9 mm ATtiny1616 board that fits on top of a USB-C connector

Dieu-de-l-elec's AngstromIO is an incredibly tiny open-source development board based on Microchip's ATtiny1616 MCU. Measuring just 9.0 x 8.9 mm, the board is barely larger than the edge-mounted USB Type-C connector that powers it, making it ideal for highly space-constrained embedded projects. Despite its tiny footprint, AngstromIO packs a QFN20-packaged ATtiny1616 MCU, two addressable SK6805-EC15 RGB LEDs, and includes access to various usable GPIOs, including I2C, UART, and UPDI for programming. AngstromIO specifications: MCU – Microchip ATtiny1616 8-bit AVR microcontroller @ up to 20 MHz with 16KB flash, 2KB SRAM, 256 bytes EEPROM USB – 1x USB Type-C port (power only, no data lines connected to the MCU) Expansion via solder pads UPDI pin for programming I2C (SDA, SCL) 2x GPIOs (PB2/TX, PA3) 5V and GND Misc – 2x SK6805-EC15 addressable RGB LEDs Power Supply 5V via USB-C port Ultra-low power consumption (down to 200nA in power-down mode) Dimensions – 9.0

@mikeolson so nice!
On the other end of the spectrum, I've just finished a super minimal colorful clock, enclosed in a wooden box as well, with only two digits.
Hours and minutes are displayed alternatively for few seconds each. I'm using an #Arduino Nano R4 and a bunch of neopixels.
I'm going to present it on March 28th for the Arduino Days 2026 at the local Arduino User Group in Milan, Italy
