It was such an accident that I bought a NUCLEO-G474 [Copy link]

 

I have always wanted to buy this board, but the spot purchase channels provided by ST official have been out of stock in China, and the overseas shipping cost is ridiculously expensive. I have been following them for several days waiting for them to restock. Today, I remembered that there is a Yunhan Core City where I can check the supply of other spot websites. I searched it with a try-it attitude, and found that they actually have a large amount of spot stock, the price is not expensive and includes tax, so I decisively placed an order and got one, and am waiting for delivery.

Maybe they just stocked up there.

It's really amazing that you found such a hard-to-buy board.

Where is this chip mainly used?

Applications are the same as other microcontrollers. It can be said to be a feature. Five independent ADCs can achieve 5-way synchronous sampling. 6 high-speed op amps, 7 comparators. 3 12-bit 1M voltage DACs with optional buffers. 4 12-bit 15M voltage DACs (for internal use, can be connected to comparators, etc.) High-precision timer 184ps 3 voltage references 2.048V 2.5V 2.95V

Yes, it took a lot of effort to buy this board

This is a great stock

Not all of them are cheap there, it depends on the model.

The performance of this board is awesome.

After comparing, stm32g474vet6 is cheaper than mouser. This is the first time I ordered from him. I don’t know how the others are. The last time I bought something from arrow, I had a pleasant experience

In terms of simulation, it is pretty good in STM32 or even in all MCUs.

In addition to the enhanced analog part, the computing power is also powerful (The devices embed peripherals allowing mathematical/arithmetic function acceleration (CORDIC for trigonometric functions and FMAC unit for filter functions).

Then the download part becomes STlink-V3.

This is also a very good improvement for stlink v3. The debugging and VCP speed have been greatly improved.

Generally speaking, it is good and the speed is relatively fast.

NUCLEO-G474 has STLINK V3 onboard, which is a good deal. It makes me want to buy one, but the total price is 132 yuan? Is it shipped directly from China?

For new users who have included tax and shipping, they can first draw a lottery to get a cash coupon. Unfortunately, I registered before. I called this morning and was told that it might be shipped from abroad because the 10-day delivery period is relatively long.

Okay, okay, awesome!

I just wanted to buy it today, but I found that the price was 132 yuan the day before yesterday, but it has become 135 yuan today. I think it is because of the depreciation of RMB. I also saw STLINK-V3MINI for sale, which is only 71.3 yuan per piece, but it is sold in batches of 2. I want to buy one, but I wonder if anyone wants to buy it together?

Registering a new user should be able to draw a few dozen yuan of coupons. The customer service who called me said that the winning rate is more than 90%.
