Raspberry Pi 4 Hat with 5-28VDC - 3A power with barrel jack input, Fan, RTC with Supercap backup, Debug UART, temp sensor and WS2812 RGB led
Description
The "PiSerialPower" Hat Power-supply Hat for RaspberryPi (and pin-compatible competitors) which also provides a rich set of features :
- 5 to 28VDC barrel jack power input
- 5V - 3A voltage regulator to power the Raspberry Pi
- a Fan (PWM controlled)
- an RTC (PCF85363) with Super capacitor backup (about one month date/time retention, and will not need to be changed in a few years !)
- a USB to UART FTDI chip (FT230XS) to give you access to the debug console using a simple, common micro-USB cable
- a reset button
- a TMP101 temperature sensor
- and a WS2812 RGB led ... well, there was some place left on the PCB ...
The serial and reset signals are also available on a 2.54mm header.
Of course, the board uses the format specified by Raspberry Pi and allows access to both FPC connectors, and is provided with mounting screws.
The board comes fully assembled and tested.

Figures 1, 2 and 3 give the different dimensions and the positions of the main elements (FAN, connectors, reset button and user led) of the PiSerialPower RPi Hat.
Connectors
The HAT has one USB connector numbered P1, a DC barel Jack connector numbered P3, and two 2.54mm pitch headers numbered P4 (Debug) and P5 (Raspberry Pi connector). Refer to figure 4 for connectors position.
Detailed description of the signals found on each connector pin follow.
Electronics
The PiSerialPower RPi Hat has been created using KiCad EDA software suite for the creation of the schematics and printed circuit boards.
