Over the last decade computer systems have become more powerful and smaller with each new generation. Here we are in the early 21st century and this trend continues. Technexion have recently released a new system on a chip (SOC) called the PICO-IMX7-EMMC, it's tiny. This little board measures 36mm by 40mm, the CPU power that this little unit has is just plain amazing.
It's based around the NXP i.IMX7 chipset and has two versions; the 800MHz solo and 1GHz Dual core unit. It utilizes up to 2 GB of DDR3 RAM and has onboard 4GB of eMMC storage. These features alone make it ideal for embedded applications where processing power is needed in a small space but it gets better.
The PICO board has a huge array of IO ports:
Edison I/O @ 1.8V
9 x GPIO
4 x PWM
2 x I2C
1 x I2S
1 x SPI
2 x UART
USB-OTG
SDIO (4-bit)
Additional I/O @ 3.3V
24 bit TTL RGB
RGMII LAN
CAN
USB Host
I2C
Operating systems that run include Linux 3.x, Yocto and Brillo.
The choice for embedded systems now is vast and with boards like the PICO IMX7, more and more power is available in a very small space.
