At CES2016, major chip makers and equipment manufacturers launched an air battle, making the emerging product form of drones a real fire. The reason is that if drones have been positioned in personal consumer applications, its The market capacity is actually very limited, and the enthusiasm of the manufacturers will not be so high, but as its demand in other application scenarios such as agriculture and logistics is continuously explored, the enthusiasm that can sweep the upstream and downstream of the industry will naturally follow. Come. This year's CES related topics related to drones are everywhere, and non-network small series can be quite proud, because domestic companies such as DJI, Yihang and other companies rely on the keen market sense to seize the opportunity to let domestic manufacturers In this market, it is very beautiful, and also masters the important discourse power in the industrial chain. But the upstream chip suppliers in the UAV market, especially the main control chip, are still dominated by European and American Korean manufacturers. Xiaobian specially counts the current mainstream 8 UAV master control chips for your reference: 1. STMicroelectronics STM32 Series At present, STMicroelectronics' STM32 series is a high-utility drone master chip in China. At this point, STMicroelectronics has a very clever approach. It has sponsored the National Undergraduate Electronic Design Competition very early. The main control chip of the man-machine project is STM32. The students are familiar with its main control platform. After working, the drone will naturally choose it. The STM32 series has a number of STM32F0/F1/F2/F3/F4/F7/L0/L1/L4 product lines. Among them, the STM32F4 series is widely used in drones. The ARMTM-based STM32F4 family of MCUs uses ST's NVM process and ART accelerators to achieve 225 DMIPS/608 CoreMark performance through flash memory at operating frequencies up to 180 MHz, which is the basis of all Cortex-M-based cores to date. The highest benchmark score achieved by the controller product. Due to the dynamic power adjustment function, the current consumption range from flash memory execution is 89μA/MHz for STM32F410 to 260μA/MHz for STM32F439. The STM32F4 series includes eight compatible digital signal controller (DSC) product lines that are the perfect combination of MCU real-time control and DSP signal processing: Advanced series STM32F469/479–180MHz CPU/225DMIPS, up to 2MB of dual-zone flash with SDRAM and QSPI interface, Chrom-ARTAccelerator, LCD-TFT controller and MPI-DSI interface STM32F429/439–180MHz CPU/225DMIPS, up to 2MB of dual-zone flash with SDRAM interface, Chrom-ARTAccelerator and LCD-TFT controller STM32F427/437–180MHz CPU/225DMIPS, up to 2MB of dual-zone flash with SDRAM interface, Chrom-ARTAccelerator, serial audio interface for higher performance and lower static power consumption Basic series STM32F446–180MHz/225DMIPS, up to 512KB Flash with DualQuadSPI and SDRAM interfaces STM32F407/417–168MHz CPU/210DMIPS, up to 1MB of Flash, adds Ethernet MAC and camera interface STM32F405/415–168MHz CPU/210DMIPS, up to 1MB of Flash, advanced connectivity and encryption Basic series STM32F411–100MHz CPU/125DMIPS, with superior power efficiency, larger SRAM and new intelligent DMA, optimized data processing power consumption (dynamic efficiency series in batch acquisition mode) The STM32F410–100MHz CPU/125DMIPS sets a new milestone for superior power efficiency performance (89μA/MHz and 6μA in shutdown mode), and uses new intelligent DMA to optimize the power consumption of data batches (using the dynamic efficiency of batch acquisition mode)? Series) with true random number generator, low power timer and DAC STM32F401–84MHz CPU/105DMIPS, the smallest and lowest cost solution with superior power efficiency (dynamic efficiency series)
Intercome speaker:
Intercome speaker is a kind of micro speaker unit which uses a diaphragm made of Mylar material. Mylar speakers are of ultrathin design and lightweight and clear voice. It is widely used in building security industry (e.g. intercom, video door phone, intelligent door control..)
There are two types of Mylar speakers from the shapes:
1) Round shapes, we have products from 10mm to 57mm in diameter.
2) Oblong shape, we have products in sizes of 1510/1712/1813-..
