ARM9 Based Linux SOM (System On Module)
Part Number: CFA-10036
Small, highly functional ARM9 based Linux SOM (System On Module). Our goals when we designed the CFA-10036 were low cost, rugged, easy to embed, ease of use, and lots of GPIO.
The CFA10036 can easily monitor several environmental sensors (temperature, humidity, etc), log the data, and make that data available over the Internet. This is the core concept behind IoT (Internet of Things). Starting with a CFA10036 makes it very easy to make your thing part of the IoT.
To reduce overall cost, we found it made sense to move the fine-pitch high-density (BGA) parts onto a small, relatively costly PCB (CFA-10036) and move the rest of the parts onto a larger, lower cost PCB (CFA-10037).
Every tech geek who saw a prototype of the CFA-10036 quickly had an idea for a project that could use it. They wanted to use it in a test fixture, in another display design, in a motion control project, or in an automotive control project.
Our unofficial motto is “If it's worth doing, it's worth overdoing.” We ended up spending hundreds of hours updating our knowledge of high-speed PCB design, and designing and laying out the CFA-10036 to maximize the performance and minimize the cost. We think the result is beautiful.
- 454MHz Freescale i.MX283 (optionally i.MX287) processor
- 289-ball BGA 17x17 grid on 0.8mm pitch
- 16-Kbyte instruction cache, 32-Kbyte data cache
- 2x CAN interfaces (i.MX287 only)
- Four synchronous serial ports
- 10/100-Mbps 802.3 Ethernet MAC (1x on i.MX283, 2x on i.MX287)
- USB 2.0 OTG (connected to microUSB AB on CFA-10036)
- USB 2.0 host controller and PHY
- 5x UART plus one dedicated debug UART
- 2x I2C (OLED shares one of these)
- LCD, touch screen, keypad, and rotary encoder support
- RTC with 32KHz crystal (requires continuous power)
- 4x 32-bit timers
- 8x PWM

- 91 GPIO (i.MX283) or 126 GPIO (i.MX287)
- 6-layer impedance-controlled PCB, gold SODIMM contacts
- On-board micro USB AB connector
- Only a single 5v supply needed (3.3v/1.8v/1.5v supplies internally generated)
