00:01STM32F407 vs STM32WB55, which MCU fits your build?
00:06So you're picking between an STM32F407 and an STM32WB55,
00:12and the price gap between the same chip across listings is way bigger than it should be.
00:16I dug through the top sellers and found the actual best deals.
00:20Here they are.
00:22First, this 5-pack STM32G0B1R86, G070RBT6, H743VIH6, F429VD6, F407VD6,
00:33and F407VGD6 and QFP and BGA, all new, $2.14 for the lot.
00:39That's about $0.43 a chip.
00:41You get 5 different STM32 families in one order,
00:45which makes it perfect for a bench full of experiments or a class set.
00:49Just know this tier is for learning and prototypes, not production runs.
00:54Next, 5 genuine STM32F407VGT6 and LQFP100, original and in stock, $24.25 for the lot,
01:03roughly $4.85 each.
01:05Higher per chip price than the singles below,
01:08but if you need 5 of them for a test jig or a few boards, this beats buying one at
01:12a time.
01:13Over 4,500 sold on this listing alone, so restocking is clearly reliable.
01:19This one is my pick for a single chip, STM32F407VGT6, high-quality, new, $3.64.
01:27You get the full 168MHz Cortex-M4F with hardware FPU, 1MB flash, 192KB RAM,
01:35plus Ethernet MAC, USB OTG, and the camera interface.
01:40That's the workhorse config for anything with networking, and one chip is one chip.
01:45Or skip the bare chip entirely and grab this STM32F407V or VGT6 development board for $3.68.
01:53The MCU, headers, and support circuitry are already wired up,
01:57so you can flash and test the same day instead of soldering a QFP by hand.
02:01Check what's included on the board, some versions ship without an onboard ST link.
02:07Note, no WB55 parts in these 5 listings, F407 only.
02:13WB55 framing kept in intro slash outro, add a WB55 listing to cover it properly.
