This tiny custom ESP32-C3 board is about the size of a USB-C connector (and is attached to one). Other features include a 32-bit RISC-V microcontrollers, WiFi 4, BT 5.0, and a single GPIO pin. It measures just 9.85 x 8.45mm. https://www.cnx-software.com/2025/11/21/ridiculously-tiny-esp32-c3-board-features-usb-c-one-led-and-a-ceramic-antenna/ #pegorKF32 #ESP32 #DevBoard

Ridiculously tiny ESP32-C3 board features USB-C, one LED, and a ceramic antenna

PegorK's f32 might be the world's smallest ESP32-C3 board. It measures just 9.85 x 8.45 mm, or slightly larger than the area covered by a USB Type-C connector. A board of this size will have limited features, and besides the ESP32-C3FH4 RISC-V WiFi and Bluetooth microcontroller, it comes with a USB-C port, a ceramic antenna, and a single GPIO pin connected to an LED. f32 specifications: SoC – Espressif Systems ESP32-C3FH4 Single-core 32-bit RISC-V microcontroller @ up to 160 MHz Memory - 400 KB SRAM Storage - 4MB flash Wireless 2.4 GHz Wi-Fi 4 & Bluetooth 5.0 USB – 1x USB Type-C port for power and programming Misc Tiny LED connected to GPIO10 Ceramic antenna Crystal Power Supply - 5V via USB-C port; 3.3V LDO Dimensions - 9.85 x 8.45 mm (the height must be around 4-5 mm) The PCB was designed using DipTrace and manufactured with a board thickness
