Description

Remark

I

1. The Shape designing size, DT20 is smaller, easy to install.

DIM: DT20:68*33*10.5mm

Market Products: 86.5*42.5*14.5 mm

2. For the mould, the surface and workmanship of DT20 are more exquisite and the products are full.

3. The internal Chip of DT20 is fixed and the device work is more reliable.

4. For the Shell Material

DT20: PC+ABS, temperature resistance 90 C.

Market products: ABS, temperature resistance 70.

Appearance

5. DT20 Chip has complete functions

6. DT20 uses advanced tantalum capacitors, which has stable performance, the Market Products uses electrolytic capacitors, low precision and explosive

7. DT20 uses industrial grade IC, reliable work, the market product uses module

8. DT20 power management shielding, less interference to the Chip, the market product's power management is open

9. DT20 uses high-rate, large-brand batteries to ensure that power failure alarms can be reported to the platform. The market products use ordinary batteries or not. Power failure can’t continue to work properly.

10. DT20 Chip design has a watchdog to prevent the machine from crashing. There is no such function in the market products.

11. The DT20 GPS chip is an industrial grade Ublox IC

12. Screen-printed internal codes on GPS ceramic antennas do not expose manufacturer resources, and do not affect the protection rights of agents to promote products. The market products Printing Model

13. The DT20 connection line is 22 #, the market product is 24 #, the line is thick, and it is smoother with the peripheral power supply.
