Screw Shield for Arduino battery charge Each one has ~18mA constant

Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies

Chain input allows reception of data from multiple Mini Maestros using a single serial receive line without extra components (does not apply to Micro Maestros)

and has 1-bit white/black and 1-bit red full display capabilities

but you could solder the wires to header pins

This is a USB AVR programmer supported by offical Arduino IDE
