April Development Board

April Development Board

Electric Imp Inc.

The April is a handy companion for your Electric Imp card. This breakout board provides just the bare minimum for Imp life support - a socket, an ID chip, and a 3.3V buck power supply for high power efficiency. Small and it's easy to integrate into products for demos or even use in low-volume production. Power can be supplied using a USB-Mini-B cable from a USB Charger or standard USB Port, though the data lines are not connected to anything. Optionally, a battery connector can be soldered to the battery pads, P+, P-.

Product Description

April can operate from any DC voltage from 3.3 to 17 Volts, and tolerates voltages down to -12 Volts. This is helpful for any application with removable batteries where they may be inserted backwards by the user. You may select between USB power and battery power by placing a shunt on the power select header. Please note that April does not have any circuitry for charging a battery and you should never short USB power to the battery pack. April uses the TI TPS62172 DC/DC Buck Power supply for 3.3V. It can provide an additional 100mA@3V3 to any boards connected to April, however if your application requires more than 100mA@3V3, it must have its own supply. The 3 pin jumper allows selection of the DC input source; jumper between the middle pin and the side labeled USB for USB power, and the other way for battery pack power (soldering the input leads onto the P+ and P- pads).
