Hi, I really like your undertaking and I do think I have competencies that may help you. Your application has long been submitted.
1x GND 3V3 (P2 with two pins 2.54mm) connector can be utilized to ability externally the WCH CH569 MCU (it is recommended to get rid of the P4/SHUNT in that circumstance It isn't obligatory given that the 3V3 LDO IC1 is guarded from reverse current)
This element is a Beta Edition and can be rewritten working with low degree method SDM TX/DM1 RX so that you can be difficult actual-time & ISO compliant, that may also take care of the emulation when using a Mobile phone...
By isolating the USB link, you defend your Computer system from opportunity voltage spikes, ground loops, or noise generated from the connected hardware.
HydraBus open up supply multi-Device for any person considering Finding out/developping/debugging/hacking/Penetration Screening for standard or Innovative embedded hardware
By making use of an isolator, you could properly talk to these equipment devoid of jeopardizing harm to your Laptop or compromising its security.
The STMicroelectronics RFAL simplifies the development of applications by encapsulating machine and protocol website facts.
HydraBus HydraFW Formal firmware for open source multi-Software for anybody enthusiastic about Understanding/developping/debugging/hacking/Penetration Testing for basic or Highly developed embedded components
For details we may also connect with ESP32 for the duration of bridge mode by connecting a 2nd MicroUSB connector on HydraBus so that you can have an other terminal to communicate with ESP32 I/O for instance to established EN pin to +three.
An USB isolator shields your Laptop or computer from voltage spikes due to lightning, motor startups, or other transient occasions.
