Description

The Universal Microcontroller Development board is intended to be a versatile breadboard-based test platform for designing and implementing new circuits. It features both DC wall input, as well as USB power to create one of several input voltages for powering circuits. It also has an on-board Lithium Ion cell with built-in charging IC to allow full battery powered operation. The design has multiple peripherals around the main solderless breadboard, which allow easy access to common externals such as LEDs, seven segment displays, rotary encoders, push button switches, and a MAX232 IC for serial communications. Each of the peripherals has female connectors available next to the breadboard for easy jumper wire connections.

The top of the design has a large ZIF socket to allow connections from any DIP package microcontroller. There are also two columns of DIP switches on each side of the ZIF socket. One set allows any of the pins on the ZIF socket to be tied directly to ground, +5V, or open circuited (disconnected). The second set of dip switches routes each connection through a 10K resistor that can be used as either a pull-up or pull-down. With this flexibility, virtually any DIP microcontroller can be connected and powered.

A set of status LEDs indicates the current power source for the system. When it is plugged into the AC or USB inputs, the on-board battery automatically charges. When disconnected from power and running on battery. An on-board battery fuel gauge IC controls an LED bar graph which displays the current percent charge of the battery. The battery itself is a 3.7V 5200 mAh Li-Ion rechargeable cell capable of delivering up to 6A of continuous current.
