2.4 Eddy-S4M v2.5

Eddy-S4M is a high-performance mini PCI type embedded module which include ARM9 processor 32MB SD

RAM, 8MB DataFlash, 10/100Base-T Ethernet port, Serial 4 Channel, RTC with Battery, MicroSD, 4ch ADC,

temperature sensor, max 34 programmable GPIO pins.

Eddy-S4M is 59.75 x 61.8mm size. If using Eddy-S4M-JIG board, user could develop their customized device

without other H/W development, which minimizing time and cost to develop.

Referring Example code and Evaluation Kit circuit allow developer to design device they want.

Eddy-S4M v2.5 is compatible with Eddy-S4M v2.1. The specification is as follows.
