Hardware Manual
The tinysys SoC is built using a QNTECH XCA7200T core board which has only the FPGA and a 256MBytes of DDR3 SDRAM. Since this is not sufficient to build a full computer system, a carrier board was designed to provide UART connectivity, USB host functions, video and audio output as well as some debug LEDs.
The current board houses a MAX3421 chip for USB host functionality, an SII164CTG64 for 16-bit DVI 1.0 output and a CS4344 DAC for stereo sound output. In addition to these, there's an ESP32-C6-WROOM-1 module connected to some pins of the FPGA, as well as two wires reserved for UART I/O. This UART connection between the FPGA and ESP32 is then routed in software to the JTAG UART of the ESP32, which in turn connects to a USB-C connector and can be used to communicate with a host PC. The ESP32 furthermore exposes a BLE connection over the air for serial port access, which allows for wireless terminal connections to the device.
