Two AAA batteries are all it takes to bring mobility to your multimedia board. Battery Boost Shield is an extension board pin-compatible with all standard-sized mikromedia boards (i.e. not the larger mikromedia+ or mikromedia 5 boards; see below for a list) and clicker 2 boards. This shield enables autonomous power supply using two AAA batteries. The board features an MCP1640 compact monolithic integrated circuit that provides +4.0V power supply voltage at about 300mA. The MCP1640 is a Step-up DC/DC Regulator with up to 96% Typical Efficiency. Note: The picture to the right shows the Battery Boost Shield installed on a mikromedia board for illustration purposes. Batteries are not included, and the board comes without the connectors installed. The connectors and pin headers are included for you to solder to your mikromedia board and to the Battery Boost. Key Features - MCP1640 Step-up DC/DC Regulator
- Prototyping area can be used for placing additional components
- Additional connection pins for easier and cleaner connections
- Power jumper as an ON/OFF switch.
Key Benefits - Compatible with all standard mikroMMB (MikroMedia Boards) from mikroElektronika
- Compatible with clicker 2 boards
- Simple integration using provided male and female 1x26 connectors
- Cost-effective solution that brings mobility and a stable power supply
Compatible Boards The pinout and shape of Battery Boost identically matches the pinout and shape of all the mikromedia boards with a green PCB. Those multimedia boards are available with a wide variety of microcontrollers, but all share the same design, LCD touchpanel, and most of the same peripherals. Here is a complete list: This shield also is compatible with clicker 2 microcontroller boards. Download Battery Boost Shield User Manual to see how to connect it to your mikromedia board. Note that the manual refers to an older hardware version. The new version, pictured above, adds through-hole pads for all the headers coming from the mikromedia board, does away with an external power input, and has a more useful silkscreen that shows GND and 3.3V pads (the 3.3V comes back from the mikromedia board, so you'll need to have it connected to utilize those pads).
