This is the third video in a 3 part series on how to connect the MinimOSD to the Naza M Lite for use on the new quadcopter we are building. • This is based on the MinNaza project wiki: • https://code.google.com/p/minnazaosd/... • See Part 1 here: • • MinNaza OSD Project Part1 (Preparing ... • See Part 2 here: • • MinNaza OSD Project Part2 (Connecting... • Addendum 1 to MinNaza OSD Project: • • Addendum 1 MinNaza OSD Project (sort ... • Addendum 2 • • Addendum 2 MinNaza OSD Project, Mount... • Battery Voltage resistor divider calculation: • (This is only if you are not using a current/voltage sensor and want to measure the voltage straight from the flight battery). • The recommended resistor divider is 10 to 1 (47k ohms over 4.7k ohms) but this only works with a voltage/current sensor.The target voltage on the output of the divider should be about 0.825 dc volts for a 3s battery (1.1vdc for a 4s battery using the provided firmware). • Formula is R1 = R2 x (Vin/Vout - 1). For a 3s battery R1 = 47k x ((12.6/0.825)-1) = 670k. • So if you use a 47k on the bottom (R2) you would need a 670k on the top (R1). • Keep in mind it's hard to find exact matching resistors so you might have to experiment. • For example with my 4s LiPo battery I ended up with 680k for the top resistor and 47k for the bottom resistor. (see video for diagram). I later changed the 47k to a 48k for a closer reading. • Character Set and XYZZW problem: • 05:40 on I actually show where to get the character set file and the trick to install it. You will temporarily have to use the UBX version of the hex firmware to upload the character set then got back to the original firmware
