Power can be applied as 3.3V via pins, 5V via its USB-C connector or 6 – 21V via pins.Īrduino has not included active power consumption on its data sheet but, according to the uBlox datasheet, module consumption is 286mA (Wi-Fi Tx 802.11n HT20 16.5dBm 100% duty-cycle) or 220mA (Bluetooth Low Energy, 0dBm, 100% duty cycle). Serial interfaces sharing these pins include SPI, I 2C, I 2S, UART and CAN (TWAI – two-wire automotive interface). There are: eight analogue pins (available in RTC mode) and 14 digital pins (21 including analogue pins).
Bluetooth LE is v5.0 and up to 2Mbit/s – “it has the option to scan and advertise simultaneously, as well as supporting multiple connections in peripheral/central mode”, said Arduino. Support is for Wi-Fi 4 IEEE 802.11b/g/n, and Arduino claims up to 500m range.
The board has a built-in antenna and is 2.4GHz only and can output 10dBm.
