Just bought (and alreday at home) the compatible Arduino™ Mega 2560 R3 board: a microcontroller board based on the ATmega2560. It has 54 digital I/O pins (14 of which can be used as PWM outputs), 16 analogue inputs, 4 UARTs (serial hardware interfaces), a 16-MHz crystal oscillator, a USB interface, a power connection, an ICSP header and a reset button.
Really hope to do something useful with it for signals and analysis, as well as fool the time during covid-19 lockdown.
