Motherboard By TECHTONICS

• The Pro Micro board is a microcontroller board based on ATmega32U4
• This Pro Micro board is equipped with 20 digital input/output pins out of which 7 can be used as PWM outputs and 12 as analog inputs/
• It has Atmega 32u4 Running At 5v/16mhz Supported Under UNO Ide V1.0.1 On-Board Micro-Usb Connector For Programming
• This 5V 16MHz Pro Micro board contains everything a microcontroller needs. You can directly connect it to yur computer and get started with uno based projects.

• The CJMCU TCA9548A I2C 8 Channel Multiple extensions development board is interesting in that it has an I2C address (0x70 by default)
• you basically send it a command to tell it which I2C multiplexed output you want to talk to, then you can address the board you want to address.
• Note that you if you happen to have I2C devices with I2C address 0x70, you will need to short one of the Addr pins on the TCA9548 breakout to Vin in order to make it not conflict. Given that you can have 0x70 thru 0x77, just find one thats free and youre good to go.

• Leonardo Board, first development board to use one microcontroller with built-in USB
• Leonardo R3 Board
• Leonardo Board

• Super High Brightness and Contrast (Adjustable)
• OLED monochrome 128×64 dot matrix display module.
• Control Chip: SSD1306
• Only Need 2 I/O Port to Control

• Two independent PWM cycle with variable Frequency and Duty cycle.
• Wide frequency range 1Hz ~ 150Khz
• The frequency and duty cycle can be controlled using switches provided on board. It can also be controlled using serial communication protocol

• Board will run from 2V to 5V.
• The latest version of the LilyPad supports automatic reset for even easier programming.
• This version of the LilyPad now uses the new ATmega328 at 8MHz.
• Use this setting when using this new LilyPad 328.
