The DiP-Pi PIoT is an Advanced Powered, WiFi connectivity System with sensors embedded interfaces that cover most of possible needs for IoT application based on Raspberry Pi Pico. It can supply the system with up to 1.5A@4.8V delivered from 6-18 VDC on various powering schemes like Cars, Industrial plant etc., additionally to original micro-USB of the Raspberry Pi Pico. It supports LiPo or Li-Ion Battery with Automatic Charger as also automatic switching from cable powering to battery powering or reverse (UPS functionality) when cable powering lost. Extended Powering Source (EPR) is protected with PPTC Resettable fuse, Reverse Polarity, as also ESD.
The DiP-Pi PIoT contains Raspberry Pi Pico embedded RESET button as also ON/OFF Slide Switch that is acting on all powering sources (USB, EPR or Battery). User can monitor (via Raspberry Pi Pico A/D pins) battery level and EPR Level with PICO’s A/D converters. Both A/D inputs are bridged with 0402 resistors (0 OHM) therefore if for any reason user needs to use those PICO pins for their own application can be easy removed.
The charger is automatically charging connected battery (if used) but in addition user can switch charger ON/OFF if their application needs it. DiP-Pi PIoT can be used for cable powered  IoT systems, but also for pure Battery Powered System with ON/OFF.
Each powering source status is indicated by separate informative LEDs (VBUS, VSYS, VEPR, CHGR, V3V3).
User can use any capacity of LiPo or Li-Ion type; however, must take care to use PCB protected batteries with max discharge current allowed of 2A. The embedded battery charger is set to charge battery with 240mA current. This current is set by resistor so if user need more/less can himself to change it.

The DiP-Pi PIoT is also equipped with WiFi ESP8266 Clone module with embedded antenna. This feature open a wide range of IoT applications based on it.

In Addition to all above features DiP-Pi PIoT is equipped with embedded 1-wire, DHT11/22 sensors, and micro–SD Card interfaces. Combination of the extended powering, battery, and sensors interfaces make the DiP-Pi PIoT ideal for IoT applications like data logger, plants monitoring, refrigerators monitoring etc.

DiP-Pi PIoT is supported with plenty of ready to use examples written in Micro Python or C/C++.
