1. NodeMCU Amica board +

2. ESP8266 SMT Module - ESP-12E, however you don't want to work directly with the SMT, but instead with the: NodeMCU = open-source firmware, may also refer to their very popular devkit board design which is available from $8 to $10

NodeMCU ESP-12E Pin mapping In Arduino, add support for NodeMCU board. (a lot of annoying GUI stuff) Then can program directly in Arduino over USB cable :)

Troubleshooting

• Does LED_blink work?

Both LEDs should blink, but alternating. Serial monitor should display low (<10) values.

• Does motor_helloworld work?

Both motors should move, specifically they should accelerate, switch directions, and repeat. Serial monitor should display commanded speed.
