ETA508 is an 8-channel standard UART serial communication expansion module, which is connected to the Innolux motherboard through a simplified ISA bus. The serial ports of ETA508 are all 3-wire (RXD, TXD, GND), 3.3V TTL. The ETA508 includes two 16C554 chips internally, and each serial port is an interrupt triggered data transmission and reception (through a shared interrupt mechanism). The ESM3354, ESM7000 and other motherboards support the expansion of 2 ETA508s, allowing for up to 16 extended serial ports.

This module can still be used with motherboards such as EM9360 and EM335x, but for new designs, it is recommended to use it with ESM335x, ESM7000, and ESM6802 industrial control motherboards.

ETA503 is a 4-sort communication expansion module based on the simplified ISA bus of Innolux, consisting of a 16C554 and a logic controller, providing 4 9-wire TTL level serial ports. The ETA503 can be connected to the simplified ISA bus of various embedded motherboard evaluation boards of Innolux through a 20 core flat ribbon cable, and can also be back plugged into the user's application board in the form of a "device". Yingchuang Company provides ETA503 data transmission and reception interrupt drivers and routines.

This module is currently available for multiple EM series and ESM series motherboards with simplified ISA bus.

ETA704 CAN bus expansion module

ISA-EVB Extended Evaluation Board

ETA704 module

ETA704 is a CAN bus expansion module. When used in conjunction with ESM series industrial control motherboards with ISA bus, it can expand 4 CAN bus interfaces. Each CAN interface signal TXD and RXD is a TTL level signal, which requires the use of a motherboard and necessary drivers (isolation optional) to form the CAN bus signals CAN_S and CAN_L.

ETA704 can be evaluated and tested on ISA-EVB V3.0.
