The H7 series is the latest high-performance ARM microprocessor of ST company, while STM32H750VBT6 is the most cost-effective one in the H7 product line. It has all the features of the H7 series, such as cortex-m7 kernel, 400Mhz main frequency, 1MB distributed SRAM, 16K instruction and data cache.128KB zero wait for Flash and so on, and the price is reasonable, best for high-performance embedded application development.

For PCB sample manufacture, JLCPCB provide 5pcs PCB sample by $2 within 2 days.
The sample picture as below;
Also, JLCPCB Provide the SMT service, start from $7,now they are sending $7 for new customers,means, you can do SMT service totally free.Unfortunatly, they can do only SMD parts, the DIP parts have to be installed by ourselves.

While i think this is a nice board, there are a few things that could still be improved - at least from my point of view.
1. The STM32H750 has great graphics capabilities. It has a LTDC unit which is able to directly control RGB lcd displays. This would allow for fast graphics. However, you choose to only provide an mcu lcd interface (16 bit ?). A RGB interface on a FPC connector would be great. Most of the RGB lcds have a 40 pin fpc connector. There are a few 'quasi standard pin assignments' around, so choosing one of these (e.g. that from Olimex) would be very useful.
2. The pcb is too big to be used on a breadboard. Also, the double row headers would prevent that. Better use single row headers and try to get the PCB a bit narrower to make it bread board compatibe.
