2018年4月9日 · It has a JL (or π) logo and the chip code is either AS18DHO171 (letter O) or AS18DH0171 (digit 0). The former search string yields some results in Google. - And why has this question been closed? The last paragraph reads like a perfectly clear question to me. \$\endgroup\$ –

2018年7月27日 · This logo is JL and stands for Jie Li (Electronics). I found JL brand. AC1513CF9J0T 1-06BT. in a very low cost bluetooth mini speaker which did not work when I purchased at HK$20 or US$2.56 for destruction to see whats it …

This question is inspired by this question. I'm interested in on-line resources which can be used to identify logos. Are there any databases of commonly and not so commonly used logos on ICs which...

2020年4月5日 · For example, here is a datasheet for the Zh-Jieli JL AC6905A that has a BT 4.2 radio. So these cheap little BT 4.2 gadgets from 2017 onward may have this generic device. It may be that buyers order a specific programming and the actual number JL stamps on the device may be tagged to the buyer.

2019年1月17日 · On the PCB Logo Creator dialog box click Load and select the BMP file. Click Board Layer and choose Top Overlay. Click Scaling Factor and experiment with sizes (1000 mils = 1 inch). Click Convert and wait. Once the conversion is complete hit the Exit button. Now you have a logo on the Top Overlay and you can use it with Copy/Paste onto a ...

These markings include: Manufacturer Logo and\or SMT code. If you are unsure of character differences, make sure these are noted. E.g.: 8 could be mistaken for B. That means if you have A32B it could be mistaken for A328. If you're unsure, you will need to search for both. Here are some sources where you can find them: Digikey SMT ID; SMT codebook

2015年8月10日 · Create logo using a vector editor (I used OmniGraffle, but Adobe Illustrator or a free vector tool like Inkscape should also work) and save as a Vector PDF. Open the bottom silk Gerber file (my CAM job names it bottomsilk.ger) into Cenon. Import logo PDF file onto a new layer (there's a selection for that in the import dialog).

2023年8月23日 · It's possibly a JL (杰理芯片) AC7911BB MCU. The datasheet doesn't say anything about markings, but from what I've seen on other JL ICs, the characters after the dash seem to match with the last characters of the part number. This is the only one I could find that ends with 1BB and is in a QFN48 package.

The chip says JL AP24186-26A4, but I can't find datasheet anywhere. Every time it takes me to dead end. If someone know about it then please help. Update: Found that it's Bluetooth 5.0 based audio
