WRTnode is a small and low cost development board powered by Mediatek MT7620N and running OpenWRT.
The developers have been working on three new OpenWRT boards based on Mediatek or Hisilicon processor and featuring either an M.2 connector, a mini PCIe connector, or support for H.265 camera.
The first board is WRTnode2P with the following specifications:
SoC – Mediatek MT7628an MIPS 24KEc processor @ 575 MHz
System Memory – 256 MB RAM
Storage – 32MB Flash
Connectivity – 802.11 b/g/n WiFi @ 300 Mbps (2T2R)
I/Os via NGFF M.2 connector:
PCIe X1, USB 2.0 host, SD-XC
5x 100M Ethernet switch
I2S up to 192K/24-bit
2x UART, SPI, I2C
20x GPIO
Dimensions – 42 x 22mm
The second board, WRTNode2R, features a processor and a micro-controller, and can be connected to a mini PCIe port:
SoC – Mediatek MT7688an MIPS24K Processor @ 580 MHz
System Memory – 256 MB DDR2
Storage – 32MB NOR Flash
MCU – STMicro STM32F103 Cortex M3 micro-controller
Connectivity – 802.11 b/g/n WiFi @ 300 Mbps (2T2R)
I/Os via mPCIe connector (preliminary, exact details are TBC):
Mediatek processor
PCIe X1, USB 2.0 host, SD-XC
5x 100M Ethernet
I2S up to 192K/24-bit
2x UART, SPI, I2C
4x PWM
20x GPIO
STM32 MCU:
5x 12 A/D
26x GPIO
10x PWM @ 36 MHz
CAN, 3x timer
Dimensions – N/A
The third and last board, WRTnode Hi, is a little different because it’s a WiFi camera board powered by Hisilicon Hi3516A:
SoC- HiSilicon Hi3516A ARM Cortex A7 processor @ 600MHz with NEON and FPU
System Memory – 512B DDR3
Storage – 32MB SPI Flash
Connectivity – 802.11 b/g/n WiFi
Camera Support
Up to 5MP sensor
H.264 / H.265 multi-stream real-time encoding
H.265 up to 2560×1920 @ 30 fps at 4 Mbps
I/Os via mPCIe edge connector
2x SAR-ADC
4x UART interfaces
IR, I2C, SPI master, I2, GPIO
8x PWM interface (four independent, four multiplexed with other pins)
2x SDIO 3.0 interface with support for SDXC
1x USB 2.0 HOST / Device interface
100/1000Mbps Ethernet
Dimensions – N/A
The board also runs OpenWRT, and an SDK will be provided to handle the camera.
