Commercial lighting solutions

 上海巨微藍(lán)牙芯片增強(qiáng)現(xiàn)實(shí)(AR)游戲槍解決方案
Application case description:
• Multi-channel, > 16bit pwm
• OTA function
• Constant power supply, no power consumption requirements
• Flash frequently erases and records the state of the lamp to prevent power failure.
• BLE_MESH/ proprietary MESH/2.4G bottom interface
• Millimeter-wave radar scene requires MCU to have strong computing power (FFT).
 
Advantages:
• 2.4G interface open.
• BLE Flexible Customization OTA
• 26bit/16bit pwm
• Large-scale commercial success stories

Smart meter solution

Application case description:
• BLE is convenient for users to recharge directly, which is very convenient compared with the traditional IC card method.
• BLE can use local networking to realize low-cost centralized reading/monitoring of users' electricity consumption.
• BLE OTA facilitates firmware maintenance and solves problems.
• No low power consumption requirements
• Use ble local networking centralized copy, and individual users need NBIOT/cat1 centralized copy.
• If the power consumption is calculated by GPIO external interrupt, it can respond to the interrupt when writing flash.
• Some have LCD requirements.
 
Advantages:
• Provide flexible local networking mode to facilitate customers to realize local centralized reading.
• Single chip solution of BLE+LCD
• A large number of successful cases

Bluetooth water meter solution

 

Application case description:
• BLE is convenient for meter reading, (NB-IOT has 5% bad signal), and Bluetooth centralized reading cost is low.
• The maintenance is convenient, and the traditional infrared has high requirements on the shell technology, and its use is relatively limited.
• Users can directly recharge (can be drawn)
• Low power consumption, design > 6 years (no battery replacement, worse environment)
• Most of them need to add LCD
• Usually you have to bring NBIOT or LORA copy, and some of them don't, just use ble copy.
• The mechanical watch obtains water through Hall.
• Ultrasonic meter obtains water quantity through serial port.
• Infrared communication /125K smart card communication (optional)
• The space of water meter circuit board is small, and the integration scheme is more urgent.
 
   

Instrument Solution for Electric Vehicle/Scooter

 
 
Application case description:
• Multiple IO requirements
• Need to write flash frequently, and when writing flash, need to respond to interrupts
• Bluetooth proximity unlock required
• Need to receive remote control and tire pressure data
• Some require voice playback
 
Advantages:
• More IO
• Write flash that can respond to interrupts
• Bluetooth proximity unlock
• 2.4G and BLE run simultaneously, providing flexible reception of remote control and tire pressure data
• Can play voice with only 2 IO and an external amplifier costing 2 cents
   

Bluetooth medical detection related solutions

 
Application case explanation:
• Applications include blood glucose meters, oximeters, blood pressure monitors, thermometers, drug/alcohol/virus rapid testing
• Biochemical analysis generally uses electrochemical detection, which is completed by using operational amplifiers in conjunction with ADCs to measure test strips
• LCD is generally required, with a higher number of points required
• Long certification cycle for medical products
• CGM products have relatively high market expectations in the future
 
Advantages:
• Low power consumption
• Unrestricted export certification
• QFN48 package, with more 40 GPIO pins, offers more choices compared to general transparent transmission, and can be used as SOC
