E78 series SMD SOC modules
[Interface]：USB
[Size]：70*36mm
[Introduction]：E78-400TBL-01 is a test kit specially designed for E78 series SMD SOC modules, combined with USB to TTL serial port backplane. E78-400TBL-01 leads all the pins of E78-400M22S for customer testing and development, which greatly reduces the difficulty of customer testing and development.
