I think the measurement range can be increased by changethe component parameters. Why do you need a wide measurement range?

the easy way is  to use  Remote   +   Receiver Module  + Relay Module

Yes, but you can only use ioxx, not the definition method of Arduino Dx, Ax

you can try read IO34.

Very interesting. What scenario is this product used in?

Can I navigate without looking at my mobile phone?

Fermion: DFPlayer Pro - A mini MP3 Player with On-board 128MB Storage (Breakout)

Can this product meet your needs？

Very interesting product, can you introduce this product?

PCB is two layers.Dielectric material is FR-4.

The output voltage of the pin VCC is equal to power source's voltage. (Output USB voltage when powered by USB, output battery voltage under 3.7V lipo battery input)The VCC port usually is not used as the power supply port of the mainboard. If you have to use that port to power the mainboard, then the battery input pin should be left floating.

I think the battery can only be charged through the USB interface.

If you supply power to esp32 through VCC, you cannot connect VB and usbvcc.

The size of this 7-inch screen is similar to that of the 6-inch screen.

What products are you making?

Does the product have to use a smaller screen?

Here is the frequency band supported by sim7600ce

TDD-LTE B38/B39/B40/B41FDD-LTE B1/B3/B8

Canadian network: 

Rogers   LTE-FDD B2, B4, B5, B7, B12, B17

Bell         LTE-FDD B4, B7

Telus      LTE-FDD B4

Therefore, this product cannot be used in Canada.

I found an extension. Is this  what you want?

I think you can check the definition of MX-5 OBD.

Usually, OBD is defined as this

this is DFRobot  CAN shield circuit diagram，  It uses the  DB9 port.

A DB9 to OBD cable is required. There are two cable sequences in the market.

Type A

Type B

this is DFRobot  cable ,  it is  type B

P1 DB9 Female   P2 OBD II male  1         ——      5  2         ——      4  3         ——      6  4         ——      7  5         ——      14  6         ——      10  7         ——      2  8         ——      15  9         ——      16

I don't know what the wire sequence of MX-5 is and what cable should be used.

What kind of cable do you use？
