Ultra-compact IoT board

The KEHIPI ESP32-C3 SuperMini is an ultra-compact development board built around the ESP32-C3 Wi-Fi and Bluetooth 5.0 dual-mode chip. Its single-sided surface-mount design keeps the footprint minimal for space-constrained projects. The board delivers a 32-bit RISC-V CPU running at 160 MHz with 400 KB SRAM and external QSPI flash expansion. It suits developers creating low-power IoT and wearable applications.

Upgrade from larger modules

This board replaces bulkier development platforms when physical size and power draw are the limiting factors. The jump is worth it when a project demands integrated Wi-Fi 802.11 b/g/n and Bluetooth 5.0 LE in a form factor that fits inside small enclosures. It also moves from older single-protocol boards to a single chip handling both wireless standards with a floating-point unit for heavier math.

Build integration needs

The board provides 11 GPIO pins supporting digital I/O and PWM, plus 4 ADC pins for analog sensors. Communication options include UART, I2C and SPI for peripheral expansion. An external antenna improves signal strength in tight spaces. On-board reset and bootloader buttons simplify development workflows. The design frees up PCB area and power budget for batteries or additional sensors in compact devices.
