Introduction to Allwinner A133 Industrial Control Core Board
Dingchang's editorial team believes that for industrial control environments, the B2B board-to-board connector of the core board is relatively secure, with low power consumption and heat generation. It can operate at low temperatures without fan cooling, and its anti-misinsertion design is well-implemented to prevent incorrect connections. The pin pitch is a high-density small spacing of only 0.5mm, with all core board hardware resources provided by 160 pins. The cost of repairing or replacing the connector is also low, making it the preferred choice for customers who have requirements for both cost and maintenance in industrial control equipment.
Other functional introductions are as follows:
Dingchang's brand-new DC_C133 Allwinner quad-core A133 1.6GHz core board provides core board resource connections through B2B board-to-board interfaces. It features a secure interface, strong anti-vibration performance, and a compact size, with a PCBA dimension of only 50304.8mm. The 6-layer PCB design offers hardware resources including up to 2GB LPDDR4 and 32GB eMMC internal storage. It has been adapted to the Android 10 system and is mass-produced. Sample testing is welcome.
The pin definitions for all 160 pins of the A133 are shown in the table below:
