HDMI output, touch and microSD for Unit PoE-P4
M5Stack AddOn Display Out is an HDMI output module for the Unit PoE-P4. The LT8912B chip converts the MIPI DSI display signal into HDMI, which you can view on a monitor connected to the type A socket. You choose between 1280 x 720 px at 60 Hz and 1920 x 1080 px at 30 Hz.
The board also has a touch panel connector, a microSD card slot and a USB type A port for a mouse or keyboard. The module receives 5 V directly from the Unit PoE-P4 expansion connector.

How the module connects to Unit PoE-P4
The 24-pin FPC cable with a 0.5 mm pitch, included in the set, carries the MIPI DSI signal to the module. You use it to connect the Unit PoE-P4 display connector to the module input.
On the underside, the module has SDIO-Bus 9-pin and ISP-Bus 6-pin connectors with 2.54 mm pitch, which plug into the Unit PoE-P4 expansion connectors. Through them, the controller supplies 5 V, the microSD card SDIO bus and the USB type A data lines.
Touch, microSD card and USB port in one module
- The 6-pin touch connector carries the I2C bus as well as the reset and interrupt lines of the touch controller
- A card in the microSD slot can store graphics, interface assets and configuration files
- You can connect a mouse or keyboard to the USB type A port, which delivers up to 0.5 A at 5 V
- The HDMI type A socket accepts a standard HDMI cable for an external monitor

Programming in Arduino IDE and UiFlow2
The M5UnitPoEP4HDMI driver has been part of the M5GFX library since version 0.2.24, so you do not need to install it separately. The manufacturer's examples show a bar chart, an image from the microSD card and graphics downloaded over Ethernet.
In UiFlow2 and MicroPython, the DisplayOut library handles the HDMI output. You will find programs for the Arduino IDE and the list of required libraries in the manufacturer's documentation.
Botland is an official distributor of the M5Stack module family in Poland. We have extended this system of stackable functional devices with accessories from our range and numerous blog guides. All M5Stack products presented here are original.
Is it the right choice for you?
A good choice if:
- You are building a terminal with an HDMI monitor on Unit PoE-P4, powered over Ethernet
- You are creating an HMI control panel with touch or with a USB mouse and keyboard
- You want to display graphics stored on a microSD card or downloaded from the network
Consider another option if:
- You need HDMI output for an Atom module: Atomic Display Base - M5Stack A115
- You prefer an ESP32-P4 controller with a built-in touchscreen: Tab5 - M5Stack C145
Did you know?
A single Ethernet cable powers the whole set
The Unit PoE-P4 supports PoE power compliant with IEEE 802.3at, so data and power reach the controller over a single Ethernet cable. The AddOn Display Out takes 5 V from the controller expansion connector, so it runs from the same cable and does not need its own power supply.
Frequently asked questions
What resolutions does the HDMI output support?
Two modes: 1280 x 720 px at 60 Hz and 1920 x 1080 px at 30 Hz. You select the mode in the program code, and the monitor must support it.
How does the module connect to the Unit PoE-P4 controller?
With the 24-pin FPC cable from the set, connected to the display connector, and with the SDIO-Bus and ISP-Bus pin connectors. Through the pin connectors, the module also receives 5 V power from the controller.
What libraries does the module need in Arduino IDE?
The HDMI driver is in M5GFX from version 0.2.24. The manufacturer also requires M5Unified from version 0.2.18 and the M5Stack board package from version 3.2.6.
