HaneSOM: Smallest Linux System on Module (20mm x 20mm)

DAB Embedded a Belgium based embedded design house has launched probably the smallest system on module running Linux.

Features

1. Size: 20mm x 20mm x 2.5mm(H) and Weight: ~3grams
2. Microchip’s ARM Cortex-A5 (SAMA5D2) core running at 500Mhz with NEON engine
3. 128MBytes DDR2 memory
4. 32Mbit / 4 MBytes of QSPI Flash (onboard). For Linux, external SD card or eMMC is needed.
5. Peripherals (69 I/Os)
   • LCD TFT support (24bit RGB) (Resolution upto1024 x768
   • 5 Mega Pixels CMOS camera sensor interface (12 Bit Parallel)
   • Audio interfaces (SSC, I2S)
   • Capacitive touch controller
   • USB 2.0 High speed ports (OTG and Host)
   • 10/100 MBit Ethernet MAC (external phy is required)
   • MicroSD memory interfaces
   • Other interfaces like SPI, I2C, UARTs, CAN-FD, 12-bit ADC, PWM, GPIOs etc.
6. Possible to run in low power mode
7. RTC clock
8. Operating Temperatures: -40 to 85 Degree C
9. Operating voltage: 3.3V +-8%

Software support:

• Bare metal SDK
• Embedded Linux + Uboot

Boot time (~30-35 Seconds)

Power Consumption

While interacting with Art Staliarou, CTO of DAB Embedded I got to know a few details on power consumption:

1. Linux running, idle (no commend running) = 160mA @ 3.3V
2. Video capturing from OV5640 sensor = 250mA @ 3.3V
