4-Channel 5V Relay Board Arduino Nano Development Board compatible 32-Bit ARM Power: SAMD21 Cortex-M0+

32-Bit ARM Power: SAMD21 Cortex-M0+ at 48 MHz delivers significantly more processing headroom than 8-bit Arduino boards

Standard 830-point and 400-point solderless breadboards

suitable for both indoor air quality monitoring and industrial hazard detection

A six pin header can be connected to an FTDI cable to provide USB power and communication to the board

This design principle is critical in drone applications where voltage sag directly impacts motor performance
