MAPIO hardware is based on multiple electronic boards to facilitate repair. It is based on a Raspberry Pi Compute Module 4, adding integrated circuits and connectors to enhance features.
PCB1 is mandatory, and provide the following functions :
Socket for Raspberry Pi Compute Module 4 (eMMC variants only)
Slot for an M.2 SSD (2242 or 2280)
1x USB-C 2.0
1x USB-A 2.0
Internal USB-C connector for debug purposes
Optocoupled UART input for TIC (Linky)
RS485 10 Mbps transceiver
250V 10A relay
5V Fan connector
Jumpers for power supply selection
Jumpers for Wifi/BLE/BOOT configuration
PCB2 is optional, but delivers the full potential of MAPIO :
A 18650 backup battery, providing several hours of autonomy in case of power loss
3 slots for (optional) RF modules
2.13” black and white ePaper
3 RGB LEDs
3V3 DC-DC converter
MAPIO has been designed to be installed on DIN rail. The case is a customized version of Bud DMB-4773.
You need to have at least 6 free spaces (108 mm) on your switchboard for MAPIO, plus space for AC-DC power supply. 9 free spaces are recommended.
Electrical specifications and installation
MAPIO has to be powered by a 5V DC, 2A power supply. The power input connector is on the upper left side of the casing.
You need to use the provided Wurth 691361100002 connector.
Connect the output of the AC-DC converter (for example, Mean Well HDR-30-5) to J1001 connector.
Note : the use of a 2A circuit breaker upstream of the AC-DC converter is highly recommended.
