Tips & Notes
- on M9N-G4-3100, The 3 magnetic coils have little solder paste to avoid the excess to “tilt” them, resulting in some reading inaccuracies of the compass. Any strong impacts will definitely separate them, especially the “tall coil” Sen-Z-f. Pls use this precision module with care.
- Start with ubx GNSS FW3.01, timepulse is aligned with UTC time and that time is set valid only after leap second is downloaded. That could take up to 12.5 min. Probably PPS LED will not blink immediately after GPS has 3D fixed.
- The M9N-G4-3100 provides the ability to reset the receiver. Bridging “M9N-RST” pad to Ground for at least 100 ms will trigger a cold start. RESET will delete all information and trigger a cold start. It should only be used as a recovery option.
- No barometer integrated.

Smells great
Scent: Aquatic
The fragrance is perfect. Not too heavy not too light. Kinda smells like designer cologne, I’m not going to mention the name.

For dry pits, this is it!
Style: Casked Vanilla, Size: 2.65 Ounce (Pack of 1)
This stuff works great. I used to use the Dove Men+ but they changed the formula and it did not work as well for me
This formula (aluminum zirconium tetrachlorohydrex gly) works phenomenally keeping the under arms dry and the Casked Vanilla is a nice, long lasting scent. Easily lasts all day and still smells fresh after 36-ish hours. I have not experienced any irritation. Glad I found this product!

Strong scent, strong protection
Style: Italian Bergamot, Size: 2.65 Ounce (Pack of 1)
I’ve been using Cremo Deodorant for Men with the 48‑hour sweat and odor protection, and it does a genuinely good job of keeping me dry and fresh through a normal workday and into the evening. The formula goes on smoothly without tugging, feels comfortable on the skin, and I haven’t noticed irritation or marks on my shirts, which is a big plus if you wear darker colors. The scent is classic Cremo: richer and more layered than a typical drugstore stick, so you get a more “cologne‑like” vibe rather than a basic soapy smell.
In terms of performance, it holds up really well for office, errands, and casual activity, and you only really start to notice it fading after a long, hot day or heavier workouts. If you run very hot or do intense outdoor work, you might want to reapply or pair it with a body spray, but for most day‑to‑day situations the protection is more than enough. Overall, if you like bolder, sophisticated scents and want something that feels a step up from basic antiperspirants without complicating your routine, this stick is easy to recommend.

Smells Incredible and Actually Works!
Style: Palo Santo, Size: 2.65 Ounce (Pack of 1)
’ve tried a lot of men’s deodorants over the years, but this one from Cremo — Palo Santo Antiperspirant & Deodorant — really stands out. The scent is next-level: smooth, woodsy, and just a little bit exotic without being overpowering. It smells high-end, almost like a cologne you’d pay good money for.
Performance-wise, it absolutely delivers. I stay dry and fresh all day, even through long work hours and workouts. The 48-hour protection claim actually holds up — I’ve gone a full day and into the next morning without any trace of odor or stickiness.
It also goes on smoothly, doesn’t leave white marks on dark shirts, and doesn’t have that waxy or powdery feel some antiperspirants do. The packaging feels premium too, which fits the Cremo brand.
Bottom line: If you want a deodorant that smells incredible and actually performs like it says it will, this one’s worth every penny. Palo Santo is now my go-to scent — masculine, clean, and unique.
