Summary of SIPEED LAUNCHED ALL-NEW TANG NANO 4K BOARD FOR $12
Sipeed released the Tang Nano 4K development board featuring Gowin GW1NSR-LV4C LittleBee FPGA and an Arm Cortex-M3 core. Compared to the original Tang Nano, it offers 4608 LUTs, 3456 registers, camera (OV2640) and HDMI interfaces (up to 720p), 180K SRAM, 256K flash, two PLLs, four I/O banks, and USB-C power in a compact 60 x 22.86 mm form factor.
Parts used in the Tang Nano 4K:
- Gowin GW1NSR-LV4C FPGA (LittleBee series)
- Arm Cortex-M3 processor
- OV2640 camera interface
- HDMI display interface
- 180K SRAM
- 256K flash memory
- 2 PLLs
- 4 total I/O banks
- USB Type-C power port
- Board PCB sized 60mm x 22.86mm
There had been a spoiler by Sipeed a few weeks back about the testing of yet another Tang Nano board. Yes, you are right, this is not the first Tang Nano board by Sipeed, but the first version came two years ago as a $5 development board built around Gowin GW1N-1 LittleBee FPGA. Electronic hardware leader Sipeed has released the Tang Nano 4K board featuring Gowin Semiconductor’s LittleBee series GW1NSR-LV4C FPGA.
The board has a powerful upgraded version of the Gowin’s LittleBee FPGA and a hardcore processor of Arm Cortex-M3 that was missing from its predecessor. Also, when compared to the first release of Tang Nano, the new module has 4608 LUTs which is more than 4 times. Tang Nano 4K board features significantly more registers to 3456 compared to 864 in its predecessor.
Specifications Of Tang Nano 4K Board:
- FPGA: Gowin GW1NSR-LV4C
- LUTS: 4608
- Register: 3456
- Multiple Parameters: 16
- SRAM: 180K
- Flash memory: 256K
- PLL: 2
- Total I/O bank: 4
- Processor: Arm Cortex-M3
- Camera interface: OV2640
- Display interface: HDMI
- Dimensions: 60mm x 22.86mm
- Power: USB Type-C port
With its minimalistic design, the board is shipped with camera and display interfaces via default OV2640 interface and HDMI respectively. However, with the 32-bit Arm processor, you can expect decent performance with a slight delay in video interfacing. Note that the manufacturer is not too sure if the HDMI interface can do video-in as the Gowin official demo is for output. Also, the HDMI interface is capable of giving a maximum video resolution of up to 720p.
