1. 0 the charging circuit on Cuhead V2 0 will disconnect 2 No external power for Arduino then the charging circuit of Cuhead V2 0 is working and the battery will power the boards Normally we give power to Arduino directly thus the charging circuit is inactive 1 2 2 Add Potentiometer The new added potentiometer is to adjust the voltage to any value needed by adjust AMSIII7 Vin to 5 6V 6 0V It is hard to do so by fixed resistance The default voltage of Cuhead V2 0 has been set in the right voltage normally you don t have to adjust it 1 2 3 Increase the Flash memory chip The increase of the Flash memory chip is serial interface of the Flash memory chip it can work in 2 5 V 2 7 V can be used as program code data storage Flash memory chip and Arduino are used together SPI interface the speed can be up to 66 MHz It contains 17301504 bytes is organized for 4096 page each page 512 or 528 bytes In addition to main memory the Flash memory chip also includes two SRAM data buffer each buffer 512 528 bytes When main memory is programming buffer 1s allowed to receive the data and to support data stream write And the Flash memory chip allow simple in the system to programming without having to input high programming voltage It can through the CS Enable and through the three line interface SI SO SCK in data communication Because Cuhead V2 0 Flash memory chip and Arduino uses the same SPI interface we through the Cuhead V2 02.
