1. Introduction
"wishTree" is a quick prototyping and PoC development board that enable makers to use all
IoT connectivity options- WiFi, Bluetooth, BLE, LoRa and 2G on a single board. It comes in
ESP12 and ESP32 variations.
It will help numerous enterprises, engineers, innovators, hobbyist and advanced users to
build and test any idea before serious money or effort is put in. Wish any use case, and build
the MVP in just hours without much ado.
The board is built by wiseThingz after 3 years of IoT deployment experience. We know the
pain points. So all the fine points have been taken into consideration while building it.
2. Brief feature set
Notable features are as follows:
Credit card sized board
Runs 5v and 3v3 on-board to connect all types of sensors and displays
Wired communication: I2C, URAT, micro-USB, RS485
Wireless communication: WiFi, BT, BLE, GSM, LoRa
Micro-amp level deepsleep
Power connections: Screw terminals, USB,
Powered by: AA-battery, LiPo with CC-CV charger, Mobile charger, Solar panel
On-board 1.5A MOSFET switch; low-amp transistor switch
Coding through Arduino IDE
Free breadboard space

USP: A compact PoC board to quickly deploy a concept with finished look. With jumper
combinations, it facilitates efficient GPIO usage, enable low power deep-sleep by detaching
all peripherals during sleep for longer battery life.
