Micro Gearmotor - 175 RPM (6-12V) Shipping:4-6 Days and can also be used

and can also be used to launch and update code via the bootloader

though the actual available output current is a function of the input voltage and efficiency (see the Typical efficiency and Maximum continuous output current sections below)

more mounting options

probably up to 5Km with directional antennas and settings tweakings

but also BLE protocols and you can now talk to the modules over UART or SPI as well
