Vvyomagami Hi all, can anyone suggest me autofocus camera module with USB protocol

techielew•3/13/24, 2:56 AM

What's the use case? And what stage of development are you in? If you're looking for a USB-based eval module, you could check out Arducam: https://www.arducam.com/?s=usb&id=98994. They have a decent selection of affordable evks. If you are looking for something more professional it may be good to look into a higher end camera and combine it with a carrier. Connect Tech Inc creates such carriers and they have partnerships with commercial-grade camera manufacturers. lmk which direction you're thinking.

Someone who has been working on a lot of this type of stuff is @Yash Naidu but he's been busy for a while. Let me see if I can get him to jump in for a bit.

What parameters specifically are you looking to adjust?

Its better to go with regulator of higher capacity about 1A. If you have some inductive load then current consumption could be high at startup and this could bring supply voltage down, causing digital circuit to reset or go to error states, so better to go with regulator of 2 to 3 times of peak current

Hi gKarthik good to hear from you. @Navadeep might be able to recount some of his experience to set you on a path but @JohnBudweiser and I had a conversation about this a while ago and he suggested getting started with ModelSim. Then Navadeep jumped in with a free web version: https://www.makerchip.com/.

Combine this with some foundational reading and QA with the experts here and I think you have a good set of tools to get started. But please let us know if you have specific questions.

An MPU6050 from Digikey for $8 (about 640 Rs). But when I got the breakout board for it from Robu, it only cost me $1.4 (around 113 Rs). Why is there such a big difference in price?

Usually, surface-mount components like the MPU6050 are cheaper. So it's surprising that it's more expensive on Digikey.

Joseph Ogbonna•3/13/24, 9:12 AM

It depends on how long the device will be on at full capacity. Literally I will say you should get another regulator of 1A, which will cover all your power requirements so that there won't be a power flunctuation in your board.

Navadeep•3/13/24, 3:21 PM

Two things:

The breakout you're seeing definitely is having a clone. * *coughs** You know where they come from.
And also to note is the volume price. At 1K units, the price easily cuts to about half and if recurring volume purchase is promised, the vendor will be happy to give you a special price - not shown in digikey. So the breakout board manufacturer would have made volume purchase (multiple tape/reels) to make their offering competitive in the market.

I've heard this interesting thing that all these >45nm process chips cost about 0.1$ per die in volume fab. Whatever the complexity is. Rest some for packaging and a huge margin $$$

nour_oud•3/13/24, 4:50 PM

Hi! if you are looking for the highest voltage under load (punch or top speed) then choose a LiPo. If you are looking for the highest capacity for the weight (energy density), choose Li-ion. If safety is a big concern, then choose Li-ion.

Marvee Amasi•3/13/24, 4:52 PM

Good day @aymen ammari , you know we attimes interchange these terms ; LiPo batteries (Lithium Polymer) and lithium batteries . LiPo batteries are actually a type of lithium battery. So for your flight, consider lookups like energy density, weight, and discharge rates. LiPo batteries are common in RC flights because of their high discharge rates.
