No.1 General-purpose IC STM32F405RGT6 with drastic price ups and downs: once a market bestseller

The price of STM32F405RGT6 surged sharply in March. Its regular price is 12 yuan, while market quotes hit 24 and 25 yuan in mid-March. However, prices began to fall back in mid-to-late March, and currently stand at around 12 to 13 yuan.

STM32F405RGT6 belongs to the base product line of the STM32F4 series, positioned between the entry-level and high-end product ranges. Like the STM32F405xx and STM32F407xx series, it is built on the high-performance Arm® Cortex-M4® 32-bit RISC core, with an operating frequency of up to 168 MHz.

At the beginning of March, news spread that ST had extended its delivery lead time and raised quotations for certain part numbers, driving up the popularity of ST chips in the spot market.

The STM32F405 series stood out among them, and STM32F405RGT6 once became a top trending chip in the market.

Nevertheless, its market momentum began to decline in mid-to-late March, with both price and popularity dropping noticeably at present.

    No.2 Viral Chip ICM-42688-P with Price Cut in Half: Still Remains Highly Popular

The viral chip ICM-42688-P saw a price drop and even a halving in late March. Market quotations once reached 70–100 yuan in March, but have now plunged sharply to 35–40 yuan.

Even so, this component remains highly popular in the spot market, staying high on the hot search list. There are still numerous buying and selling inquiries circulating in industry groups.

This chip is a six-axis inertial measurement unit (IMU) launched by InvenSense, a subsidiary of TDK. It integrates a 3-axis gyroscope and a 3-axis accelerometer, targeting application scenarios that demand high motion accuracy, such as wearables, AR/VR devices, robots, and drone flight control systems.

According to information from OscarLiang in the technical community, FPV drone gyroscope solutions have undergone multiple iterations. Starting from 2023, the ICM-42688-P gradually replaced previous generations by virtue of its advantages in price, supply availability and performance. After early design defects were confirmed to stem from circuit issues at flight control manufacturers, the part was officially recommended by Betaflight, quickly becoming the new industry standard.

Reviewing the price trend of the ICM-42688-P: market demand began to pick up quietly starting in September 2025. Its regular price of 9 yuan surged all the way up, doubling to 23–28 yuan in November. Amid a market sentiment boom in January 2026, quotes peaked above 70 yuan. Prices continued climbing after the Spring Festival and hit a high of 70–100 yuan in March.

Subsequently, news of the original manufacturer releasing hundreds of thousands of units reversed market sentiment and triggered a price decline. Ahead of the Qingming Festival, the target price of this component had already fallen to 35 yuan. Currently, prices fluctuate widely, with market quotes ranging from 35 to 40 yuan.
