V1.0 Attaches to a ESP32-DevKitC-V4, check pinout to make sure it coincides.
It's meant to drive three (or less) 3.3v motors, max 1A per PWM output. Use with Li-Po or Li-Ion 3.7v nominal voltage batteries.
Connects to a Blynk.io server, which can be self-hosted, otherwise, use the free Blynk Cloud server or contact me for a spot on mine.
Mobile app can be recreated by scanning the following QR code on the Blynk phone app:
Hardware files are in the eRos directory, meant to be edited on KiCad v5.0 or higher.
Firmware files are in the Psyche directory, if you open the project on PlatformIO it should load all required Arduino libraries automatically, else, here's a list:
- shaggydog/OneButton@^1.5.0
- ayushsharma82/AsyncElegantOTA@^2.2.5
- ottowinter/AsyncTCP-esphome@^1.2.1
- ottowinter/ESPAsyncWebServer-esphome@^1.2.7
- bblanchon/ArduinoJson@^6.17.3
- s00500/ESPUI@^2.0.0
- khoih.prog/Blynk_Async_ESP32_BT_WF@^1.2.1
- adafruit/Adafruit BMP280 Library@^2.4.1
- teckel12/NewPing@^1.9.1
- gamegine/HCSR04 ultrasonic sensor@^2.0.2
- adafruit/Adafruit_VL53L0X@^1.1.1
Firmware.bin must be built with the huge_app.csv partition scheme.
Have fun!
