Necesito mejorar el circuito adjunto, agregando un chip rs485 alimentado por el bus, un bus rs485 con 10 slots, 1 bus 5 V debajo del VUSB en los tres espacios, dejando los espacios medios e inferiores con desconectables o apagables con una señal digital (3.3V high) como pueden ver en la foto. El bus para el RS485 puede ser añadido a la derecha de la placa y se puede usar el espacio superior o medio para el chip. En las otras fotos, se añada un opcional, de existir factibilidad, y es añadir un chip INA al mismo pcb, pero enfocado en que se le pondrá un conector fácil que se conectará a un USB C.
