The Trax is a WiFi-enabled Tracked Vehicle Platform.
Based on the Kraft module, it allows driving two DC motors from 4.5V to 13.5V at up to 1.2A each.
An ESP8266 module (ESP-01S) is included for WiFi communication.
Though flexible and accepting any power supply between 4V and 6V, the platform is designed to be powered from 6 AA cells, organized in two packs of three cells each, amounting to around 4.5V.
Two 5mm LEDs are included and connected to GPIOs (P24 & P25).
The platform also features some prototyping space and breaks out some GPIO and communication interfaces.
- Power input: 4.0V - 6.0V
- 10x GPIO, including 2x PWM (P0-P7, P20, P21)
- PWM A: P18
- PWM B: P19
- FWD A: P28
- REV A: P29
- FWD B: P27
- REV B: P26
WiFi (ESP8266) Connection
- Enable: P8
- Flash: P9
- Reset: P10
- LED 0: P24
- LED 1: P25
