Re: FrskyX Smartport telemetry supported on Ersky9x9xt?

Hi Mike! I'm on ar9x board with the latest ersky9x test firmware and X series RX. There is still I have SWR=32 all the time. And often, when I power cycle my TX, I get not right RSSI reading. It shows 37 for RSSI and not changing the value. After power cycle it often fixes and shows correct RSSI, bu...

Re: OpenXSensor for DLG with 1S LiPo

I have yet to start with Arduino and therefore a lot to learn. I might be missing a lot, but anyhow.... Can you tell me why you don't have these 2 PCB's on top of each other?? It was not an option in my case. I have very narrow space in mine DLG. To have them on top each other will not fit. But if ...

Re: custom PCB

Wow! Looks very good! What is the purpose to separate VIN on SP connector and BAT + pin on BAT connector? Should they be interconnected? Or at least to have a Bridge that can be shorted to connect them together? Also, maybe you can rotate on connector to have both GND pads square. :) What do you thi...

Re: OpenXSensor for DLG with 1S LiPo

So, today I had a test of my OpenXsensor vario.
Works very well, stable and adequate readings, so no need any additional stabilization of power or decoupling.
Today was quite windy about 10m/s.
Had a flight for 21 minute with max altitude at 54 meters.
Excellent tiny vario!

OpenXSensor for DLG with 1S LiPo

I have 1m DLG with FrSky receiver. There is not much space left in the fuselage, but I want to install Altimeter. OpenXSensor very good candidate.

Re: custom PCB

Yeah, dedicated LDO reg for pressure sensor is enough, no need of additional cap. 8-) But in general I think it would be nice to make the device working from 1S LiPo. For this you can use 3.0V LDO (with less than 200mV dropout, for example MIC5501) or without LDO, and use 8Mhz resonator. But then vo...

Re: RX voltage alarm in 2.1

Sometimes I'm using only battery without BEC, for example in small DLG. But then I treat it as Battery voltage, not as Rx voltage.
So, for me, removing Rx battery alarm makes sense.

The reason I started with this project was to provide a voice module that is easier to build for those who can't do fine soldering.

Hi João!
I'm comparing your schematic to others, and I see that some designs have pulled up D1 (MTD) line to +5v with 10k resistor.
Your schematic do not have it. What the purpose of this resistor? should I add it?
