What internal electronics does the Control+ Technic Hub (88012) use?

Question

I'm interested in comparing to the other Powered Up hubs, which are already documented here:

• Mindstorms v4 / spike prime What internal electronics do SPIKE Prime and Mindstorms v4 use?
• train 6AAA hub What electronics are inside the LEGO Powered Up hub?
• boost / move hub What internal electronics does LEGO Boost use?

Thanks!

TLG was kind enough to send me one of these, so I've done my part and cracked it open to see what is inside. The teardown was fairly easy to do without damaging any components. The only tool I used was a brick separator. 😀

There are a few tabs around the edges that can be depressed to allow the main housing to come apart:

Küçük kauçuk düğmenin amacının ne olduğundan emin değilim, ancak pil bölmesinin içinden erişilebilir. Bu, gelecekteki bir pil paketinin algılanmasıyla ilgili olabilir.

PCB basitçe kalkar:

Alt tarafta ana işlemcinin bir STM32L431RCT6 olduğunu görebiliriz . Arm Cortex M4 tabanlıdır, 80 MHz'e kadar saat hızına sahip olabilir ve 256kB flash bellek içerir.

Üst taraf, ilgilenilen bileşenlerin geri kalanını içerir.

Bluetooth Low Energy (BLE) iletişimi için Control + hub , Texas Instruments'dan bir CC2640 kullanır . Bu, Powered Up hub tarafından kullanılan çipin aynısıdır.

The motor drivers are LB1836 chips. They are dual drivers, and there are two on the board, one for each pair of ports. These are the same driver chips used for the Powered Up, Boost, and Robot Inventor hubs.

Overall, this hardware is very similar to the other hardware in the current generation of products (Robot Inventor, Powered Up, Boost, etc).
