Hardware components
In GitHub software folder there are 6 examples how to use the GPIOs, I2C, SPI (we add new library for
this as otherwise you couldn’t use the micro SD card as original Arduino library support just one SPI),
CAN, UART, SD-card, LCD3310.
SOC
is Single core Cortex-A7 ARM running @650 Mhz with Cortex-M4 running @209Mhz
is Dual core Cortex-A7 ARM running @650 Mhz with Cortex-M4 running @209Mhz
is Dual core Cortex-A7 ARM running @650/800 Mhz with Cortex-M4 running
@209Mhz
Memory
STMP15x-SOM can have 256 or 512MB DDR3L memory, powered with 1.35V, with 16 bit data bus
width and running at 1066Mhz (533Mhz clock).
PMU
STMP15x-SOM have Power Management Unit based on AXP209 IC. It allow the power voltage to
SOC core, peripherals, DDR3L memory and etc to be programmable via I2C. Special driver in Linux
take care for the different power modes.
USB
High Speed USB 2.0 Host and High Speed USB 2.0 OTG.
Display
RGB LCD display on LCD 40 pin connector, compatible with LCD-OLinuXino displays.
Audio
ES8388 Stereo Audio codec generates Audio output and takes care for microphone input.
