Description

Electric Imp Inc APRIL BOARD BREAKOUT APRIL FOR IMP | Type 802.11 b/g/n | Frequency 2.4GHz | 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. Simple Type: Test & Measurement 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).
