Hello,
I have three parts as shown in picture:
- an Arduino Nano
- a NV08C-CMS-BRD from NVS Technology
- a Tallysman TW3402 Active GNSS Antenna
What do i want to do is to first connect TW3402 antenna to NV08C board and then connect NV08C board into Arduino and finally connect Arduino into my PC with USB Cable. I'll program Arduino to read data from NV08C board and write it to serial port in order to transfer data to my PC. My problem is that i do not want to electrically damage any of these modules through connecting! you may tell me to read each module documentation, but the problem is that I've studied civil engineering in university and i cannot understand many things of their documents! Because of this I am asking you to tell me how to connect these things together.
My problem is not how to code Arduino to do what i do need because its several years that i'm a programmer, my problem is that how i can connect these modules that they work and none of them be damaged for for example higher voltage than module standard voltage.
I'll tell my noob understanding from these stuff, but if it is not true you should absolutely not shocked!!!
first of all:
NV08C-CSM-BRD datasheet
TW3402 Datasheet
In NV08C board documents it is noted that it have two jacks for antenna, one for active antenna (left one) and one for passive antenna (right one).
Also in TW3402 antenna it is noted that it is a active antenna so i have to connect it to active jack like image below:
As I've said this is an active antenna, and it need power source in order to work. right? in its documentation it is noted:
Supply Voltage Range (over coaxial): 2.5 to 16 VDC nominal (12VDC recommended maximum)
Supply Current: 10 mA typ.
And as noted in NV08C board document, pin #1 of N08C board is:
| **Pin# ** | Name | Description |
|---|---|---|
| 1 | ANT_PWR | Power Supply for external antenna |
So i have to connect power supply for active antenna to this pin#1. Is it right?
After these all, NV08C board have to connect to Arduino which is connected to PC by USB or to a battery source.
Again this is from nv08c board document:
| **Pin# ** | Name | Description |
|---|---|---|
| 2 | VIN | 3.3 VDC Power Supply |
| 10 | GND | Digital Ground |
| 14 | COM2_TX | Transmitted Data for CSM’s UART B output |
| 15 | COM2_RX | Received Data for CSM’s UART B input |
I should connect arduino to nv08c board like this:
| NV08C Board pin | Arduino Pin | Description |
|---|---|---|
| #2 (VIN) | 3V3 | |
| #10 (GND) | GND | |
| #14 (COM2_TX) | RX | |
| #15 (COM2_RX) | TX | |
| #1 (antenna power supply) | 5V |
And if i connect nv08c board to Arduino nano like table above, they hopefully will work fine together and i'll be able to program Arduino to read data from nv08c board and write it into serial for transferring to PC).
Finally this is DC Electrical Characteristics for nv08c board from its documents:
| Parameter | Minimum | Typical | Maximum | Unit |
|---|---|---|---|---|
| Supply voltage | 3.0 | 3.3 | 3.6 | V |
| Supply current* | 60 | 90 | mA | |
| Active Antenna DC Bias voltage | 2.9 | 3.3 | 3.6 | V |
| Active Antenna DC Bias current | 0.85 | - | 45 | mA |
| Power consumption | 200 | mW |
Are my statements in above text true? and am i able to connect these parts like what i've said with properly working?
Honestly i cannot pay for finding how to connect these stuff because i am creating a prototype and also these did cost me enough as prototype so i rather to learn it myself...
Waiting to hear from you guys,
And thanks for reading my story!
