Engineers working in embedded development are constantly trying to strike a balance between reliability, size, and performance. Forlinx Embedded’s recently released FET3506J-C SoM, which is based on the Rockchip RK3506J processor, has emerged as the go-to option for developers in industries like consumer electronics, smart medical care, industrial automation, and new energy because of its ultra-small size of 29mm×40mm, board-to-board connectors that allow for quick disassembly and assembly, and industrial-grade features.
Ultra-small Size of 29mm×40mm, An Ideal Choice for Compact Scenarios
The compact design of the FET3506J-C SoM makes it much smaller than traditional SoMs, measuring only 29 mm by 40 mm. Forlinx Embedded’s innovative design is the result of their effective usage of the processor pins.
The matrix IO design allows for the flexible mapping of 98 functional signals onto 32 physical pins. Through software setup, any pin can be allocated any functional signal, including FSPI, JTAG, CAN-FD, UART, and others.
The extremely compact SoM can be directly integrated onto the device motherboard without the need for an extra expansion board design in situations where space is limited, such as industrial handheld terminals and portable medical devices. It can greatly increase the products’ market competitiveness and portability.
2mm Mating Height Board-to-board Connectors – a reliable guarantee behind the 2-second quick disassembly and assembly
Two 80-PIN board-to-board connectors with a pin pitch of 0.5mm and a mating height of just 2mm physically link the FET3506J-C SoM to the carrier board.
There are two main benefits to this design:
First, the board-to-board connectors make it possible to quickly replace the SoM, which significantly lowers the cost of equipment maintenance;
Second, the connectors are designed to prevent hardware damage from improper use by preventing reverse insertion. In situations requiring frequent maintenance, such industrial control cabinets and new energy vehicle charging stations, this design demonstrates its exceptional value.
2 x CAN-FD
with ultra-stable communication performance
Because of its increased data transmission rate and bandwidth usage, CAN-FD has emerged as a crucial bus interface in domains like energy management, smart transportation, and industrial automation. Two CAN-FDs are supported by the FET3506J-C SoM.
Actual testing show that there is no frame loss when the bus occupancy rate is 90%, regardless of whether the CAN-FD is receiving or transmitting in two channels or one channel at a time.
Furthermore, there is no frame loss or error frame when the bus occupancy rate is 87% and the single-channel and two-channel channels are broadcasting and receiving simultaneously at a 1:1 ratio.
The following test data makes it clear that the FET3506J-C SoM’s CAN-FD interface performs exceptionally well in terms of communication.
Industrial-Grade Features
Reliability tests on the FET3506J-C SoM have been extensive and meticulous. According to the measured data, when operating at full load, its power consumption is a mere 0.7W.
It can pass the high-temperature environment test at +85°C while operating at full load even without any heat dissipation measures, thereby guaranteeing steady and dependable operation in challenging industrial settings.
Summary
The launch of the FET3506J-C SoM reflects Forlinx Embedded’s deep understanding of customers’ needs for compact size, high integration, and easy maintenance.
With an ultra-small dimension of 29mm x 40mm, board-to-board connectors for quick assembly and disassembly, and industrial-grade features, this SoM product offers significant competitive advantages.
For developers who pursue efficient development and long-term supply guarantee, it is a reliable choice to help you achieve technological innovation and industrial upgrading.
