Generic (unbranded)
The ESP32-C6 SuperMini is a stamp-size generic board built on the ESP32-C6FH4. It has a 160 MHz RISC-V core plus an LP core, 4 MB flash, 512 KB + 16 KB SRAM, Wi-Fi 6, Bluetooth 5.3 LE and 802.15.4 for Zigbee / Thread. USB-C goes to native USB Serial/JTAG. It breaks out 22 GPIO (7 ADC) and has BOOT and RESET buttons, a WS2812 on GPIO8, an LED on GPIO15 and 3.3 V logic, for about $7.

Board capacity includes installed memory; chip-local memory is listed separately under each processor.
Capacities use KiB / MiB (1024-based units). Firmware partitions and runtime allocations reduce application-available memory.
Product operating conditions, chip ambient ratings, package case limits and junction maxima remain separate.
Reported product dimensions may exclude protruding components. Unknown height does not establish a complete clearance envelope.
Attached generated geometry is an approximate envelope. A generated outline does not establish an electrically verified PCB footprint.

The ESP32-C6 SuperMini Dev Board is built around the ESP32-C6FH4.
22 GPIO pins are exposed. Xirkit documents 26 board pins, 22 of them with pin-level electrical limits.
No. The I/O pins are not 5 V tolerant — they run at 3.3 V logic; use a level shifter for 5 V signals. Input-high threshold: 2.475–3.6 V.
Documented output-high current per pin: 40 mA typ. Values are traced to the chip datasheet; see the pinout table for per-pin limits and conditions.
Supply range 3.3–6 V. Power inputs: BAT, 5V (3.3–6 V).
