#WiFi Pants
|
||
|
|
|
||
|
|
WiFi Pants is a WiFi and 5V boost power supply add-on board for your Raspberry Pi based around the ESP-12F. It communicates over the SDIO interface to provide WiFi capability for a direct alternative to a USB WiFi adapter for low-bandwidth applications, sufficient in most embedded projects.
|
||
|
|
|
||
|
|
Most notably, WiFi Pants can add WiFi to the Zero while leaving the USB port free, and boosts any battery from as low as 3V to 5V at up to 2A to power the Pi and any other add-ons. Only six GPIOs are needed on the Pi's expansion connector. The WiFi Pants board fits the outline of the Pi Zero, with only a small protrusion for the antenna.
|
||
|
|
|
||
|
|
A JST-PH connector compatible with Sparkfun and Adafruit battery packs is included with the board. An undervoltage lock-out prevents batteries from draining below 2.7V. A soft power switch input lets a microcontroller or switch easily turn off or on the power supply.
|
||
|
|
|
||
|
|
Along with the soft power switch input, the 5 pin header exposes the Raspberry Pi's serial console. This is great for IoT projects where there is no screen but shell access is needed for setup. The header fits the 6 pin FTDI USB-to-UART cable.
|
||
|
|
|

|
|
WiFi Pants also works great with the Pi A+, B+, and 2 models.
