The UWB module features a BLE chip, nRF52833, which serves as the main controller for the entire module. The UWB chip does not include an MCU and requires control through the nRF52833. Additionally, the module is equipped with an accelerometer sensor, as well as antennas for both BLE and UWB functionalities.
We use SEGGER Embedded Studio for ARM. It is recommended to use version 5.40C; higher versions may encounter issues.
NXP, NewRf, DecaWave, and Chixchip have all released UWB chips with integrated MCUs. There have been customer feedback regarding the performance stability of NewRf's chips. Chixchip claims to have an ultra-low power UWB chip.
Not all mobile phones can support acting as BLE slaves. When an iPhone acts as a slave, its MAC address keeps changing.
MS88SFB utilizes the nRF21540 PA. The transmission power can be configured either through GPIO (General Purpose Input/Output) or the SPI interface. GPIO configuration allows for setting the output to 10dB or 20dB within the code. On the other hand, SPI configuration allows a one-time setup with an adjustable range of 0-22dB in 1dB increments.
The LNA (Low-Noise Amplifier) gain strength of MS88SFB is +13dB, and it is not adjustable. Compared to MS88SFA, this configuration allows for a greater communication distance with mobile devices.
It supports GCC development.
1. Check if the customer is willing to remove the shielding cover and add the crystal oscillator themselves.
2.If the customer is unwilling to remove the shielding cover, they can modify the code to use the internal oscillator.
