White NB - in the industry take the lead in launching BC28 IOT laboratory evaluation version (compatible BC26) at the same time, using USB interface, the developers directly inserted into the device for secondary development, external interface debugging support, provide a full range of technical guidance, perfect the technical data and development document, can support custom development, the assessment board primarily for want desperately to learn and understand the small white NB - IOT novice, a quick start tutorial, "old drivers can also use it as a" NB - IOT mobile network testing tools,

This evaluation version has the following several performance:
1, USB interface to join the ESD protection, prevent electrostatic pulse voltage and evaluation version, such as internal USB turn serial interface chip;
2, the internal voltage regulator with low power consumption, low noise low pressure CMSO linear regulators SGM2019, it also provides low differential pressure in portable electronic equipment to extend battery life,
3, USB interface has two serial port to send and receive status indicators, used to display in serial data transmission, data transmission of light as the serial data, and a high level of speed up the development progress,
4, network status light is used to indicate whether there is a network connection, said a network connection when the light is bright,
5, a key to reset button to reset BC28 module,
6, SIM card interface to join the ESD protection, prevent static and equipment in the process of card,
7, the assessment board to set aside the BC28 2 debug serial port and I2C interface, SPI interface, dormancy awakened interface, BC28 reset interface, a dormant state testing interface, 3.3 V and 5 V voltage output interface, GND interface,
8, the back has a single SIM card slot, convenient to insert SIM card,

CodePudding user response:

Move the remote module,

CodePudding user response:

Yes, move far BC26 and BC28 module,

CodePudding user response:

BC28 is OPEN?

CodePudding user response:

Return card can get 10 points available every day! Tip: you can also teach you how to faster available points enter 10000 characters
