1 Introduction

The IDM2040-7A is an intelligent display module featuring a 7” 800x480 capacitive touch panel . The module carries the latest generation EVE4 controller BT 817 supported by a low-cost high performance RP2040 microcontroller. The on -board RS485 transceiver allows communication with Long Distance Sensor Bus (LDSBus) devices or DMX512 devices through Cat 5/6 cables over an RJ45 connector. The input power supply can be either a Type -C PD charger or a PSU via the DC-jack. The Type -C PD port is controlled by FTDI ’s latest PD controller FT232HP, with PD sink profile programmable through the FTDI utility FT_PROG. With the use of a Raspberry Pi MCU RP2040, the IDM 2040-7A module allows easy programming with various circuitpython or micropython libraries.
