DIYables ESP32-C3 Supermini Dev Board and Expansion Board Combo, 2 Sets, Presoldered

Key Features

• ESP32-C3 RISC-V Processor — Single-core 32-bit RISC-V processor up to 160 MHz with integrated WiFi and Bluetooth LE for reliable IoT performance
• 11 GPIO with 4 ADC Inputs — Dev board provides 11 digital GPIO pins (all PWM capable) and 4 analog ADC channels for sensor and peripheral expansion
• Presoldered Dev Board — Header pins are presoldered for immediate use with breadboards and jumper wires
• Low Power Wearable Design — Optimized for energy-efficient wearables, portable devices, and battery-powered smart systems
• Battery Power Expansion — Expansion board connects an external 3.7V lithium battery and supports charging it via USB
• Dual Power Outputs — VCC1 and VCC2 outputs on the expansion board, compatible with ESP32-C3, ESP32-S3, ESP32-H2, and ESP32-C6 boards
• Selectable Output Voltage — Optional solder-jumper pad lets both VCC1 and VCC2 output the full 3.7V battery voltage when needed
• 10 GPIO Pin Extension — Expansion board extends all 10 GPIO pins for convenient sensor and module connections
• Purpose-Built Pairing — Expansion board is designed specifically for the ESP32-C3 SuperMini to address its power and GPIO access limitations
• 2 Complete Sets — Includes 2 presoldered dev boards and 2 matching expansion boards for parallel builds, prototyping, or education
• ...NOTE
• The expansion board breaks out 10 GPIO pins; the dev board itself has 11 GPIO pins in total. Check your pin requirements before designing around the expansion board's pinout.
• The solder-jumper pad for the higher voltage output must be bridged manually (e.g. with solder) — VCC1 and VCC2 output a regulated voltage by default until this jumper is shorted.
• This board operates at 3.3V logic levels. Do not connect 5V signals directly to GPIO pins. Install the ESP32 board package in Arduino IDE before use.
