Flash Chip and Screen controler

Post by Egg »


I have two DSO138mini, great toy!

I plan to use them for other purposes than DSO.
The schematic answers a lot of questions, but a few are remaining:

- What is the reference / capacity of the i2c flash chip on the main board? The label on the chip (CN 1818G1E) does not help.
- Is the screen controller the same as for dso138?

Then, do you plan to sell the main board on its own for possible integration in other products?

The chip U2 is a encrypted EEPROM for protection purpose. So its part number is not released. You can replace it or remove it if the MCU is not going to run the DSO firmware.

The screen controller could be different from that used in DSO138.

Yes the main board is available for selling separately. Please contact us at jyetek@gmail.com if you need.
