Cap75T High Speed DMA Hardware Board + ESP32-S3x2 Development Board MAKCU Box + HDMI-compatible CapDMA Video Overlay Box

Cap 75T DMA Board:
- Speed: 6000+
- Note: The board is just a carrier, not containing firmware. You can burn the firmware by yourself after receiving the product.

MAKCU Development Board:
- ESP32-S3 is a high-performance WiFi and Bluetooth chip designed by Espressif, mainly used for Internet of Things (IoT) applications.
- Processor: ESP32-S3 is equipped with LX7 single core processor for Xtensa, with a frequency of up to 240MHz.
- Storage: this development board is equipped with 512KB of SRAM and 4MB of Flash storage space.
- Wireless communication: supports WiFi (802.11 b/g/n) and Bluetooth (Bluetooth 5.0).
- Peripheral interfaces: including GPIO pin, ADC, DAC, I2C, SPI, UART, etc.
- Power consumption: low power design, suitable for various IoT applications.
- Main applications: the ESP32-S3 development board is widely used in smart homes, remote monitoring, environmental monitoring, wireless communication and other fields. Its high performance and low power consumption make it an ideal choice for IoT device development.
- Development environment: developers can use ESP-IDF (Espressif loT Development Framework) provided by Espressif to write and debug code.
- MAKCU is based on the ESP32-C3 development board, which has 2 ESP32-S3 chips and provides many debugging interfaces to meet users' more development needs.


Programming Steps:
- While pressing the button on the left, insert the data cable into the leftmost USB port to put the ESP-32 chip on the left into Debug mode, and then write it through software. Similarly, the ESP-32 chip on the right also needs to press the button on the right and insert it into the rightmost USB port to put the ESP-32 chip on the right into Debug mode and write it.

Video Overlay Box Interfaces: (Please follow the instructions to connect the HDMI-compatible cable in order)
- HDMI-compatible output: to connect the main display
- HDMI-compatible 1 host: to connect the host GPU
- HDMI-compatible 2 secondary: to connect the secondary machine GPU
- Type-C: to upgrade program and inject EDID (only used during upgrades)
- DC 12V: power supply (default 12V 2A)
- Note: the host GPU cannot be directly connected to the main monitor with a DP or HDMI-compatible cable. If there is a connection, it must be unplugged.

Video Overlay Box Indicators:
- D1: Power indicator (always on for power on)
- D2: Fusion function on/off indicator light
- H2: HDMI-compatible 2 secondary machine input signal indicator (always on: normal; off: no signal)
- H1: HDMI-compatible 1 host input signal indicator (always on: normal; off: no signal)

Video Overlay Box Button Function:
- Power: power switch
- K1: short press for switching resolution in cycle (1920 x 1080; 2560 x 1440; 3840 x 2460; 2560 x 1080; 3440 x 1440)
- Note: long press and hold the K1 key for 3 seconds (hold until displayed): the current resolution and refresh rate are displayed in the upper left corner of the screen, with the host information on the top and the secondary information on the bottom.
- K2: short press for switching the upper layer image matting intensity with a total of 21 levels from 0 to 20. (default 0, level 0 also matting)
- K3: short press to restore the upper layer cutout strength to the factory default of 0.
- K4: Short press for switching the fusion function.
- Note: If you press the K4 key and the fusion light on, but there are no perspective fusion, there are two ways to solve this problem. One is to set the background color of the secondary unit to pure black; The second is to press the K2 key to enhance the RGB value.
