TPA4056 based Li Ion Battery Charger.

This used a standard USB A Male connector to be charged through a Battery Bank or Wall plug.

BOM

USB_A is USB Male Through Hole Connector

CProg, 0603 resistor 10k (for 130mA charging current) or 3k ( for 400mA charging current). Decide on value of resistor based on 1C charging speedof battery. If in doubt, use 10k.

R1 is 0603 10k pulldown resistor

R2, R3 are LED current limiting resistors, any value between 600-1k ohm should be fine.

CHG is 0805 LED of Red color

STBY is 0805 LED of Blue or Green Color

Attiny10 Programming Board is a tiny board for programming Attiny10 MCU into two programming modes. The slide swith (SW1) controls programming modes. The upper position of the switch is a high voltage (12V) serial programming mode. The downer position of the switch is a TPI programming mode. You can use the high voltage serial programming for RSTDISBL fuse resetting.

AVRDude parameters for fuse resetting: avrdude -p t10 -c USBasp -P USB -x section_config -e

Robot controller board for Raspberry Pi (Zero W)

• 4 motors
• 4 servos
• Battery voltage divider/monitor
• 6-DOF IMU (MPU6050)
• Pi <-> Arduino Communication via I2C, SPI, and UART (Serial)

Components used:

• 2x MX1508 Motor Driver IC
• 2x 4.7K SMT Resistors (Arduino I2C pull-ups)
• 1x 2.2K SMT Resistor (Voltage divider high side)
• 1x 1K SMT Resistor (Voltage divider low side)
• 1x 10K SMT Resistor (Arduino reset pull-up)
• 1x Atmega328pb (B variant has 2x I2C needed for MPU6050)
• 1x 2x20 Stacking header (You can use male or female for your project)
• 1x 2x3 SMT Header for ICSP connection (Optional)
• 1x DROK Mini DC-DC voltage converter (Make sure to set to 5V)
• 1x 1x4 Male header pins for voltage regulator (1x3 works, EN is not connected)
• 4x JST Headers for motor connections (Can use standard headers too, 2.54mm pitch)
• 4x 1x3 Male header pins (2.54mm pitch) for servos (Or 3x 1x4)

I’ll be adding code to run this at my github, http://bit.ly/RoboHAT
I ordered almost everything from AliExpress, but some of the SMT parts I had laying around
