Waveshare ESP32-C5-Pico Board Adds Dual-Band 5 GHz Wi-Fi for $8.99

Waveshare has released the ESP32-C5-Pico, a compact development board based on Espressif’s ESP32-C5 SoC in a Raspberry Pi Pico-compatible form factor. It brings dual-band 2.4 GHz + 5 GHz Wi-Fi 6, Bluetooth 5 LE, and IEEE 802.15.4 connectivity together with onboard lithium battery charging at a starting price of just $8.99.

Key Specifications

• SoC: Espressif ESP32-C5 (single-core 32-bit RISC-V, up to 240 MHz)
• Memory: 384 KB SRAM + 16 KB low-power SRAM + 320 KB ROM + 4 MB SPI Flash
• Wireless:
  • Dual-band Wi-Fi 6 (2.4 GHz + 5 GHz)
  • Bluetooth 5 LE
  • IEEE 802.15.4 (Zigbee 3.0 / Thread)
• GPIO: 20 multifunction GPIOs (Pico-compatible headers) + 7 additional I/O via TCA9554PWR expander
• Interfaces: UART, I2C, SPI, ADC, PWM
• Power: Onboard lithium battery charging circuit + 3.7 V battery connector
• Programming: USB Type-C, ESP-IDF and Arduino IDE support

Waveshare offers four variants: PCB antenna (Pico / Pico-M) or external FPC antenna (Pico-U / Pico-UM), with or without pre-soldered headers.

Why It Matters

Unlike traditional Pico-sized boards that are limited to 2.4 GHz Wi-Fi, the ESP32-C5-Pico adds 5 GHz Wi-Fi 6 while retaining Bluetooth LE and 802.15.4. This makes it ideal for smart-home, IoT sensors, controllers and gateways in environments where the 2.4 GHz band is congested.

Target Applications

• Smart home and building automation
• IoT sensors and gateways
• Zigbee / Thread devices
• Battery-powered wireless projects
• Prototyping multi-protocol connectivity
