Waveshare ESP32-C6 1.47-Inch Display Development Board w/ WiFi 6 & BLE

You can program the board using the Arduino IDE with the ESP32-C6 core installed via Board Manager, or use Espressif's official ESP-IDF framework for full low-level control. Connect the USB Type-C port to your computer; the board should enumerate as a serial COM port. Select 'ESP32-C6 Dev Module' as your target board in the Arduino IDE. For MicroPython, you'll need to flash the appropriate firmware binary using esptool.py via the serial bootloader mode.

The board is powered via the USB Type-C port at 5V DC. The operating current varies significantly based on the CPU frequency, wireless radio activity, and display backlight. With WiFi active and the display on, expect currents in the range of 100-250mA. Utilizing the ESP32-C6's deep sleep modes with the display off can reduce current consumption to microamp levels, which is critical for battery-powered deployments. Always ensure your USB source or regulator can provide at least 500mA for stable operation.

No, the Waveshare ESP32-C6 development board uses an integrated PCB trace antenna for both WiFi 6 and Bluetooth signals. There is no external antenna connector (like an IPEX or SMA) provided on this specific board variant. The range is therefore limited to the performance of the onboard antenna, which is suitable for most indoor and short-range applications. For projects requiring extended range, consider an ESP32-C6 module with an external antenna port or add an RF amplifier stage.

The microSD card slot is connected to the ESP32-C6's SPI peripheral. You will need to solder the provided header to access the GPIO pins. Typically, the SD card uses the HSPI or VSPI interface (pins like GPIO 36, 37, 35 for CLK, MISO, MOSI, and a CS pin defined in your code). Use the Arduino 'SD' library or the ESP-IDF 'sdmmc' component. Format your microSD card as FAT16 or FAT32 before use. Ensure proper power supply, as card initialization can draw a peak current.

The standard 2.54mm pitch header breaks out most usable GPIOs from the ESP32-C6, excluding pins used for the internal flash, display, and USB. The pinout is typically silkscreened on the board's PCB. You will find pins for UART (TX/RX), I2C (SDA/SCL), SPI (MISO/MOSI/SCLK), analog inputs (ADC), and digital outputs. Always consult the board's schematic from Waveshare's wiki. Note that some pins may have pull-up/pull-down resistors or be used for bootstrapping; avoid using them for critical I/O.
