2.4 Eddy-S4M v2.1 / v2.5
Eddy-S4M is a high-performance mini PCI type embedded module which include ARM9 processor 32MB SDR
AM, 8MB DataFlash, 10/100Base-T Ethernet port, Serial 4 Channel, RTC with Battery, microSD, 4ch ADC, tem
perature 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.
