Every PinoutFeed story on PlatformIO — across boards, chips, firmware, projects, kits and industry, newest first.
Earle Philhower's arduino-pico 6.3 series moves the RP2040/RP2350 Arduino core to Pico SDK 2.3.1 and raises FreeRTOS from 8 to 32 priority levels, a breaking change for anyone who sets task priorities by hand. Two bugfix releases followed, and 6.3.2 closes an AudioBufferManager DMA crash.
Read the story →An MIT-licensed, bare-metal Arduino core for Nordic's nRF54L family skips Zephyr and the nRF Connect SDK, adds native PlatformIO support in 1.0.21, and patches a macOS upload regression in 1.0.22. Thread, Matter, Zigbee and Channel Sounding are still marked experimental.
ESPHome 2026.10.0 makes a native ESP8266 Arduino toolchain the default, roughly halving cold compiles in the project's own benchmarks. It also compresses OTA images by about a third on ESP32, RP2040, LibreTiny and host, adds 20 components and ships breaking changes worth reading before you update.
Hat & Hammer's OpenMote, a programmable ESP32-S3 remote in a Wii Remote-style shell, had raised $202,165 from 1,502 backers on Crowd Supply as of Oct 20, 2026, at $99 assembled or $59 PCB-only, with an estimated ship date of Feb 28, 2027.
