SparkFun RedBoard Qwiic ATMega328P compatible with Arduino board w/ Qwiic Connector and CH340C Serial-USB Converter IC Breadboardable R3 footprint microcontroller Improved reset button
ATmega328 microcontroller with Optiboot (UNO) Bootloader. Rev3 shield compatible..
Program with a USB Micro-B cable using the Arduino IDE platform: Plug in the board, select “Arduino UNO” and you’re ready to upload code.
Hardware peripherals you know and love: 20 Digital I/O pins with 6 PWM pins, 6 Analog Inputs, UART, SPI and external interrupts.
Broken out the SDA, SCL and IOREF pins, so it will be compatible with future shields Power over USB or through the barrel jack 7 to 15VDC.
The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong..

PCA9685 16 CH 12Bit PWM Servo Motor Driver Board Controller IIC Interface for Arduino Raspberry Pi Zero/Zero W/Zero WH/2B/3B/3B+ and Robot (2pcs)
Contains an I2C-controlled PWM driver with a built-in clock. It means, unlike the TLC5940 family, you do not need to continuously send it signals tying up your microcontroller.
5V compliant, which means you can control it from a 3.3V microcontroller and still safely drive up to 6V outputs, which is good when you want to control white or blue LEDs with a 3.4V+ forward voltage.
Supports using only two pins to control 16 free-running PWM outputs – you can even chain up 62 breakouts to control up to 992 PWM outputs..
3 pin connectors in 4 groups, so you can plug in 16 servos at one time (Servo plugs are slightly wider than 0.1" so you can only stack 4 adjacent ones on 0.1"-hole female headers..
12-bit resolution for each output - for servos, that means about 4us resolution at an update rate of 60Hz..
