A: Yes, it is highly suitable for these outdoor and energy-related scenarios:

• As a smart transportation motherboard: The wide temperature design adapts to outdoor traffic signal controllers, ETC toll collection equipment, bus on-board monitoring terminals and driving test systems. The fanless structure effectively reduces dust accumulation failures in harsh outdoor environments, and dual network ports support multi-device data synchronization.

• As a charging pile motherboard: The wide voltage (9-24V) + wide temperature characteristics perfectly match the working environment of new energy charging piles and energy storage system controllers. Multiple GPIOs can directly control charging guns, status indicators and alarm devices, and 4G wireless expansion enables remote operation, maintenance and data upload.

Q7: What advantages does PCM-B351D have as a smart grid motherboard and IoT system motherboard?

A: It has four core advantages for smart grid and IoT applications: ① 7×24 hours uninterrupted stable operation, adapting to unattended scenarios such as substation monitoring and environmental monitoring stations; ② Dual Gigabit network ports + 4G wireless expansion, supporting reliable remote data transmission and equipment management; ③ Multiple serial ports can connect to electricity meters, environmental sensors and data collectors simultaneously; ④ Ultra-low power consumption design reduces long-term operation costs. It is the preferred hardware for embedded industrial PC solution providers to build edge computing and IoT systems.

Q8: Can PCM-B351D be used as a face recognition system motherboard and medical device motherboard?

A: Yes, it meets the hardware requirements of these application scenarios:

• As a face recognition system motherboard: Multiple high-definition display interfaces support real-time image output, USB interfaces can connect to high-resolution cameras and card readers, and GPIOs can link access control gates, electric locks and alarm systems. The wide temperature design also adapts to outdoor access control terminals and community security systems.

• As a medical device motherboard: The fanless design reduces noise and dust pollution in medical environments, with stable operation and low failure rate. The rich IO interfaces can connect to various medical testing peripherals, meeting the hardware requirements of conventional medical embedded devices.

Q9: Which operating systems is PCM-B351D compatible with? Is secondary development convenient?
