Summary
The PICDEM™ Lab II Development Board is a development and teaching platform for use with 8-bit PIC® microcontrollers (MCUs). At its center, a large prototyping breadboard enables users to easily "experiment" with different values and configurations of analog components for system optimization. Several external connectors allow for user-customizable expansion, while our library of labs and application notes enrich the development experience. The PICDEM Lab II Development Board is also fully compatible with our latest software development environment.

Embedded Development Powerhouse
The original PICDEM Lab Development Board has remained one of the most popular development tools for PIC MCUs since its introduction. Microchip has taken this concept and expanded it for 21st century embedded development. The PICDEM Lab II Development Board supports any 8-bit PIC microcontroller (6-, 8-, 14-, 18-, 20-, 28- and 40-pin footprints), and provides an expansive array of connections for programming, I/O, analog and communications interfaces. The PICDEM Lab II Development Board will be a valuable resource to engineers across a broad spectrum of specialties, from analog designers looking to explore the power and flexibility of MCU-based systems to engineering professors seeking a flexible and relevant teaching tool that they can add to their curricula.

Hardware Flexibility Enables Experimentation
In keeping with the original, the PICDEM Lab II Development Board was designed to give you a simple development experience without the hassle of and expense of building a custom PCB in the early stages of your project. You can design a system with one or several PIC MCUs, since power and programming connections are replicated across all of the available sockets. Off- chip connections can be made in any manner, and the expansive breadboard provides a convenient area to add analog signal conditioning and drive components to a design. Three separate power supplies give the capability to provide fixed or variable voltage to a system. With several industry-standard interfaces in addition to a system of configurable conntectors, the off-board expansion possibilities are abundant.

This reference design is targeted at space-limited portable applications. The devices in the design operate from either a USB port or AC adapter. The solution has a single power output that charges the battery. A system load can be placed in parallel with the battery as long as the average system load does not keep the battery from charging fully during the 10 hour safety timer. The reference design is charged in three phases: conditioning, constant current, and constant voltage. In all charge phases, an internal control loop monitors the IC junction temperature and reduces the charge current if an internal temperature threshold is exceeded. The charger power stage and charge current sense functions are fully integrated. The board function has high-accuracy current and voltage regulation loops, charge status display, and charge termination. The pre-charge current and termination current threshold are programmed via an external resistor on the bq24040. The fast charge current value is also programmable via an external resistor.
