Description

The APF28 is a simple and low cost Single Board Computer targeted for small GUI, communication and control process.

Here is a list of the main features:

  • Processor: i.MX28x (ARM9 @ 454MHz)
  • RAM: DDR2 400. 64 to 512MB. 16 bits data bus. Default capacity is 128MB.
  • Flash: NAND. 256MB to 4GB, 8 bits data bus. Default capacity is 256MB
  • Ethernet: onboard Physical (ready to use Ethernet 10/100Mbit link)
  • USB: High speed USB OTG (OnTheGo) with onboard Physical
  • USB: 1 High speed Hosts with integrated PHY
  • Touchscreen controler (4/5 wires)
  • Low speed ADCs (up to 7)
  • High speed ADC
  • RTC and Watchdog
  • Battery charger (Li-On/Li-Po)
  • Supplies: high end DC/DC converters and LDOs on board. Only one external supply required (5V, batterie or 3.3V).
  • Mechanical dimensions: ~43x25mm

All the i.MX28 peripherals (LCD, SDIO, SPI, 6xSerial, I2C, 2xUSB, PWM, etc...) can be accessed through two high density Hirose connectors.
