Overview
Tang Console is an another dock board for Tang Mega 138k SOM and Tang Mega 60k SOM. It is designed to be small and compact, and is mechanically compatible with the Raspberry Pi 5 PCIe HAT. In addition, it also contains two 5Gbps USB3 device interfaces and two 2x20-pin header connectors, two PMOD connectors. It can meet the needs of IO expansion and high-speed communication at the same time.
At the same time, it is also specially designed for retro games. Maybe you can turn it into a retro game console, or even a handheld, whatever you like.

Hardware Resources
Getting Started
Note that Tang Mega 60k & Tang Mega 138k is currently not supported by the education version, and you need to download V1.9.11 or a newer version of the commercial IDE for use.
Lic can be applied on the Gowin official website, or you can use the online Lic service provided by Sipeed. In the IDE, select Float Lic and fill in the following information:
---Server 01---
ip: 45.33.107.56
port: 10559
---Server 02---
ip: 106.55.34.119
port: 10559
if the ip not work, try use "gowinlic.sipeed.com" domain's IP.

Precautions
| Item | Precautions |
|---|---|
| Chip Model | The specific model of the FPGA chip used by Tang Console 60K is GW5AT-LV60PG484AC1/l0,
and Tang Mega 138K is GW5AST-LV138FPG676AC1/l0. Please select the package model PBG484A & Device Version: B in the IDE. |
| Static Electricity | Please avoid static electricity hitting the PCBA; release the static electricity from your hands before touching the PCBA. |
| Tolerance Voltage | When using GPIO pin headers for external communication, ensure that the IO voltage is 3.3V. Excessive voltage will permanently damage the PCBA. |
| FPC Socket | When connecting the FPC soft cable, please ensure that the cable is completely and correctly inserted into the socket without any deviation. |
| Plug and Unplug | Please completely power off before plugging and unplugging. |
| Avoid Short Circuit | Please avoid any liquid or metal touching the solder pads of the components on the PCBA during the power-on process, otherwise it may cause a short circuit and burn the PCBA. |

Frequently Asked Questions (FAQs)
The system does not recognize the onboard debugger
Click for details
- Make sure the USB cable is connected to the port marked with *MCU*.
- Try connecting directly to the computer instead of through a USB HUB.
- Try using a better quality USB cable.
- Try another computer to rule out the computer being the problem.
- Try update to the latest firmware and try again.
The UART of the onboard debugger cannot be used
Click for details
- Try reinstall FTDI drivers.
- IF the actual baudrate is always four times the set baudrate or the UART continuously outputs garbled characters. try update to the latest firmware and try again.
