electric imp, inc 1. Product description 1.1 General description The imp is a complete wireless network node in a module. It is available both in a memory card form-factor (imp001) and in a solder-down module form-factor (imp002). It works in conjunction with the imp service to allow easy connection of any device to the internet. 1.2 Features • 802.11 b/g/n WiFi • 20MHz 11n channels, 1 x 1 • +16.75dBm max output power (802.11b) • -97dBm typical sensitivity (1Mbps) • Integrated antenna with 2.

Pin mux In addition to acting as a GPIO, each pin on the imp002 can be configured to one of several specialized functions. While pins may only have one function at a time, they may be reconfigured during run-time to change function as needed. For example, a pin may first be configured as a DAC and then reconfigured as an ADC.

electric imp, inc I/O input leakage current VSS ≦ VIN ≦ VDD 4 µA [1] WiFi requires 2.5v minimum for operation, but user code can run at 1.8v. The POWER_EN pin is driven to enable an external boost converter that will provide 2.5v+ during WiFi usage. [2] 400mA current is during worst-case TX events. These are a maximum of ~4.8ms long (802.11b 1Mbps) 8.
