The size of the module measures 132.7mm (L) x 93.5mm (H) x 26mm (W). **Figure 1 - IDM2040-43A Module - Front View** **Figure 2 - IDM2040-43A Module - Back View** Copyright © Bridgetek Pte Ltd 5 **IDM2040-43A Datasheet Version 1.0** Document Reference No.: BRT_000420 Clearance No.: BRT#203 **Figure 3 - IDM2040-43A PCBA - Front View** **Figure 4 - IDM2040-43A PCBA Back View** Copyright © Bridgetek Pte Ltd 6 **IDM2040-43A Datasheet Version 1.0** Document Reference No.: BRT_000420 Clearance No.: BRT#203 ## **Key Features:** - BT883Q EVE chip for graphics, touch and audio controller - Raspberry Pi RP2040 microcontroller - External Quad-SPI Flash with eXecute In Place (XIP) - Type-C USB port for power and data (and for reprogramming Flash) - One 40-pin 0.5mm pitch FPC connector for LCD interface - One 6-pin 1mm pitch FPC connector for capacitive touch panel interface - One 4-position 1.5mm JST male connector for 8-ohm 1W speaker - Micro-SD card socket - Two 4-position 1mm pitch JST male connectors (Stemma QT/ QWIIC) for I2C peripheral interface - One 9-position 2.54mm Harwin male header for SPI peripheral interface - One 6-position 2.54mm Harwin male header for mating with IDM-RS232 or IDMRS485 daughter boards. - One 6-position 2.54mm Harwin male R/A header for mating with FTDI TTL cables (e.g., TTL-234X-5V) - One 2x5 10-position 2.54mm Harwin male header for GPIO/PWM/ADC interface - One 3-position 2mm Harwin male header for ARM Serial Wire Debug (SWD) port - Bootsel button for entering USB device mode - Hardware Reset Button Copyright © Bridgetek Pte Ltd 7 **IDM2040-43A Datasheet Version 1.0** Document Reference No.: BRT_000420 Clearance No.: BRT#203 ~~————e—e—ee— ss)...~~ ## **3.2 Power supply** There are 2 options for powering the IDM2040-43A module: - 5V/0.5A USB Type-C connector - CN3. - Or 5V/0.5A 1x6 position 2.54mm Harwin male header CN4/CN5. Both power inputs are summed using Schottky diodes so the source with higher voltage will be use to power the system and back flow current will be blocked. Power will then go to the DCDC Buck switching regulator to output the 3.3V supply for powering up the system. ## **3.3 Microcontroller- Raspberry Pi RP2040** The Raspberry Pi RP2040 microcontroller unit used in the module has the following key features: - Dual ARM Cortex-M0+ @ 133MHz - 264kB on-chip SRAM in six independent banks - Support 8MB of on-board Flash memory via dedicated QSPI bus - Type-C USB port supporting USB2.0 Full-speed device function; reprogramming the Flash can be achieved by simply dragging and dropping a file onto the RP2040 which appears as a mass storage device. - 26 multi-function 3.3V General Purpose I/O (GPIO) with 23 GPIOs being digital-only and 3 ADC-capable GPIOs. - 3-pin ARM Serial Wire Debug (SWD) port; the standard Serial Wire Debug (SWD) port can reset the system and load and run code without any button presses as well as for debugging purpose. For full details of the Raspberry Pi RP2040 MCU, please refer to the RP2040 Datasheet. ## **3.4 Connectors & Buttons** **Figure 5 Connectors and buttons on IDM2040-43A** Copyright © Bridgetek Pte Ltd 8 **IDM2040-43A Datasheet Version 1.0** Document Reference No.: BRT_000420 Clearance No.: BRT#203 Connectors and buttons of IDM2040-43A are described in the following sections. **Note:** All GP(IO)s stated below can also be configured as GPIO or PWM. **CN1** is a 4-position connector header for audio output to 8 ohm/1W speaker and external audio line-in input. **==> picture [346 x 58] intentionally omitted <==** **----- Start of picture text -----**
