as it was stated in my previous post, now miniEMC2 supports two platform: mini2440 and mini2416.
The second one is based on the S3C2416 MCU, that is very close to S3C2440, but it's more contemporary.
So what is at this small PCB:
- 400 MHz S4C2416 MCU
- 128Mb NAND Flash
- 64Mb DDR2 RAM
- Ethernet 10/100Mb (w/o connector)
- AC97 Audio codec (w/o connector)
- 2 USB1.1 HOST (w/o connector)
- 2SD card controllers (w/o connector)
- Small TQFP120 package (40mm x 40mm)
- Power supply 220V->3.3/5/5V
- RJ45 Ethernet connector
- 2 USB HOST connector
- SD card connector
- RS-485 driver with galvanic isolation ( optional )
- Buffers for digital input/output allow direct connection to TTL-level chips, like stepper drivers L297, A3986, TB6560
- 22 TTL-compatible Digital Output
- 15 TTL-compatible Digital Inputs
- Thanks to integrated power supply and TTL drivers user have an whole CNC controller in a single board, when for mini2440 user needs to add external power supply and make/buy an expansion board.
- 2 USB HOST allow to connect USB Flash driver and another device, like a small keyboard for jogging control.
- Digital interface's connectors placed from one side of the board that simply board integration into enclosure.
At the present time mini2416 is under test from HW and SW sides. We need to know if such a board is interesting to users.
