ESPBoost

Introduction

The ESPBoost is an ESP32 shield combines a MPU6050 (3-axis gyro/accelerometer, via SDA/SCL GPIO), 2 H-Bridge motor drivers (L9110s, via GPIO 5, 16,17,18 ), and a DC-DC (4.5V ~17v to 5V) power regulator (for powering up the ESP board via USB, allowing to charge Li-Po and the ESP32 MCU). Attaching this shield onto a Lolin32, actuations that demand high current (max. 800mA for each bridge), for example, driving two DC motors, and detections of angles, acceleration can be easily made possible.

Components

Dual L9110s (800 mA) DACs
MPU6050 Accelerometer and Gyroscope
TPS563201 Voltage regulator (4.5v to 17v input, 3A output)
FSR (force sensitive resistor) connector (A2 section)

To-do

Include support for ESP32 minikit
Incoporate daisy chain support for ESP boards (e.g. TTGO T-Base) that come with an i2c connector (consisting ofSDA/SCL/3.3/GND )
Add ESPBoost-Input, configured with 3-axis gyro/accelerometer (MPU6050), 12-pin capacitive sensor (MPR121q), FSR pull-down resistors
Add ESPBoost-Actuation, consisting of 2 sets of TB6612FNG
Add ESPBoost-Power, supporting battery charging, regulating voltage from 3.7V to 5V, 9V, 12V
