Naze32 Acro to Naze32 Full

Barometer and Magnetometer

Back in September last year I wrote about the Naze32 Acro that I bought from HobbyKing. I hoped they will offer the full Naze32 version with the MS5611 barometer and HMC5883L compass, but this didn’t happen. I decided to upgrade my Naze32 Acro to Naze32 Full. But if soldering is not for you, you can find a Naze32 Full here.

The MS5611 barometer, HMC5883L compass and 16Mbit flash chip cost about 10$ incl. shipping from Aliexpress.com.

  • HMC5883L compass from GY-271 Board and even use the capacitors later on the Naze32.
  • 25P16VP 16Mbit flash chip

Needed capacitors (μF – Micro farad).

  • 1x 4.7μF
  • 1x 0.22μF
  • 3x 0.1μF

Needed tools: Heat gun/Hot air gun, tweezers, hands free item holder. Optional: solder paste.

Before you start it is not bad to download the datasheet for the MS5611, the HMC5883L and the 25P16VP. Check out these datasheets to see where is the Pin1 on the downside. On the picture below you can find how to position the sensors and the capacitors (open the original file for better resolution, not the thumbnail).

How to do it: put very small amount of solder paste on the empty pins of the board or solder these with the solder iron. Position the parts on the board and apply heat with the hot air gun on the downside of the board. It took me about 20 – 30 seconds on 450 C to melt the solder paste. It is a bit tricky to place all this small sensors and caps right, but that is how it is with SMD. Note: I haven’t bought and soldered the 16Mbit flash chip. If you have done everything right, now you have upgraded your Naze32 Acro to full Naze32 for about 10 $.

    What capacitor you need to put behind flash chip? 🙂 Because full Naze have it.

      Hey Lukas, I am not sure. Maybe 4.7uF. You actually should be able to use it without. Best, Sergey
