Doublechecking: perimeter sender assembly

Hi,

Got the parts from the shop and about to start assembling perimeter sender.
As I'm learning (everything, including soldering on the go), I want to double-check some things before getting into making HW (I'm more software person).

According the schema in https://github.com/Ardumower/ardumo...ossen/Platinenbilder/Sender_v2 Schaltplan.pdf DuoLED are connected in Green-Red and Red-Green sequence, but if I understand correctly images here: https://www.ardumower.de/index.php/de/forum/ardumower-platinen/586-ardumower-sender-board#6419 they are connected Red-Green and Green-Red sequence.
- Which one is correct (or I get the pins wrong)?
I understand that the difference will be the colors reversed, but ... still I would prefer green, when it should be green without re-soldering or changing software settings unnecessary :)

- Is it correct that INA169 has always to be bridged to 5A as it is shown in https://www.ardumower.de/index.php/...er-board-was-geht-da-schon-und-was-nicht#9231 ?

- I'm not sure that I get the pins to be connected on INA169 board right, but I assume that it should be Ok if connected as shown in https://www.ardumower.de/index.php/...er-board-was-geht-da-schon-und-was-nicht#9231 (bottom row and two top pins)?

- Resistors on the boards are all the same, except one (at least kit has 6 same and one different kind of)? (curious, because some pictures looks like have several types of resistors on them)

Thanks,
Romualdas
 
Partly figured out myself:

- So far (in current software version) they are not used, so not much difference (figured out while debugging soldering issues :) )
- for INA169 5 pins that sit in the row should be just enough (or so it looks like) and at least once in the wiki http://wiki.ardumower.de/index.php?title=Perimeter_sender_(English) it states `To detect the robot, a current sensor (INA169, 5A) is connected between the charger and the charging pins`. So it looks like 5A is a must.
- As for the resistors, one has bigger resistance because its purpose to show 12V, others are smaller
 
About the led's, I think you are right...
For the INA, I have the blue one, (https://blog.adafruit.com/2012/12/28/new-product-ina169-analog-dc-current-sensor-breakout-60v-5a-max/) I think with this one, you don't have to make the bridge, because it's 5A...
For the pins, if you check the backside of the board, the 3 rows are connected, so I suppose you can choose, depending on the type of INA you have.
Resistors are 6 x 220 Ohm (red-red-black) and 1 x 560 Ohm (green-blue-black) (R2)
