Anchor3 SoM

ARM Cortex A7 Dual Core SoM

The Anchor3 is a highly-integrated System-on-Module that utilizes an dual-core ARM Cortex-A7
processor,DRAM, Flash memory, a hardware Secure Element , 4-way MIC interface with ECNR,
and a wired/wireless communication options such as 802.11a/b/g/n/ac,
Bluetooth 4.1(Classic+BLE) and ethernet as well,and all of which are put into an compact
footprint. The various standard digital control interfaces support external sensors and higher
performance peripherals to expand the module’s capabilities.
With the combination of Wi-Fi, Bluetooth, the Anchor3 is the perfect choice for IoT / embedded
and industrial equipments, while also supporting effective price/performance capability with
4-channel MIC interface and ECNR for voice recognition application.
The hardware based Secure Element works with the ARM TrustZone, H/W Crypto accelerator,
Secure ROM/RAM an additional secure feature provide enhanced end-to-end security.
It support video input and display out support options also.

Anchor3 Station

Single Board Computer with Anchor3

Anchor3 is a small single board computer with Anchor3 System-on-Module. This is popularly
used for IoT based applications and Industrial equipments by connecting peripherals like sensors,
networking, microphone for voice recognition.
You can use several OSs like Tizen 5.0, Linux Ubuntu, Yocto etc.
This board provides SPI, I2C, I2S and UART and GPIO as Standard I/O, USB, Ethernet, WLAN/BT
for connectivity, Audio/Video In/Out, LED for indicator and User Function, Buttons for Power/
Reset/Genreal Purpose, etc.
This can access the on-chip hardware i.e. GPIOs for developing an application. By accessing GPIO,
you can connect devices like LED, motors, sensors, etc and can control them too.
This board is only compatible with Anchor 3 SoM module that is ARM based dual core Processor
along with on-chip GPU (Graphics Processing Unit).
