    Hi, They were out of stock earlier honest. (but i had not scrolled down the page to see the .stl file) I have lots of different headers etc. I am fairly sure the only items i will need to order are the display and trim pots. but i will check it all out later

    Hi Chris, I received the PCB today thank you. i just have to wait for the display you used to come back in stock. Also what trim pot did you use / recommend? and can you put the 3D files up for the box so I can slice and print my own please.

    Hi Chris, I haven’t calibrated the RPM sensor yet I have just connected it to a test rig and checked the numbers go up and down as the motor speeds up, I will be mounting the senor to a model very soon and then using my handheld optical RPM sensor to find the correct scaling factor as it depends on the number of poles in the motor. In the config_basic I just have “#define CALCULATE_RPM YES” As you need this for it to send the telemetry from what I understand the rest is setup by using a calculated sensor in OpenTX but I will let you know. I thought a about temperature but it seems to only support the analogue pins on the Arduino and not on the ADS1115 so I have no pins free however I guess that if I don’t have a Baro or ADS1115 I could use pins 4 and 5 or have two oXs sensors.

    Here is my latest sensor with a MPXV7002 airspeed sensor using A0 and A1 with a voltage divider on the ADS1115. The ADS1115 connects to the same pins (A4, A5, VCC and GND) as the GY-63. I also have a Hobbywing RPM sensor which measures the pulses from any two of the output wires from the brushless ESC. The RPM sensor connects to PIN8 on the Arduino and takes it’s VCC and GND from the second SPORT connector. I am also using PPM via the SPORT protocol to reset the Airspeed and to change between different vertical speeds calculations using compensation from the Air Speed sensor controlled via LUA scripts. Next I think I will try and create a 6S version with additional 100nf capacitors to ground try and stabilise the cell voltages. I will also use the ADS1115 to do the Current Sensing using an external HGLRC XT60 connector. But I need to get to grips more with Eagle PCB design software first. Chris did you use Eagle to design your PCBs?

    Hi, You will only see cells in the telemetry discovery screen try searching for FLVSS individual cell voltages for information about how to display each cell or click the link below https://openrcforums.com/forum/viewtopic.php?t=7266 The stars appear as it reads the value of each item and is normal. P.S. if you have a Horus using OpenTX there is a nice widget you can use on the Telemetry screens called BattCheck that will display the voltage and pack % graphically.

    Hi looking at your HGLC XT60, I can see the potential divider fine but what is the resistor on the other side between the negative and the current sensing output for. Also can you confirm what resistor values you using for the potential divider? I think this is probably for 4s and the resistor values are probably: 2.7K to Ground 15K to Positive 47K for the resistor on the other side Edited By Paul Lewis 3 on 13/05/2019 12:15:11

    I got some boards from someone who bought some of your first batch, and have completed building one, it works perfectly ( I had to wedge some header pins in to test the voltages, I thought I already had some 4S JST-XH connectors but I only had 3S and 6S so I have ordered some) I have sandwiched my MS5611 between the Arduino and the PCB board.

    When you order another batch please put me down for 4
