Product Details

Product Description

SIM68RB is a support for the 2 generation Beidou module, you can support both the 2 generation and L1 GPS band receiver and analytical positioning. This module uses MT3333's MTK platform, which has the characteristics of low power consumption, high sensitivity, high positioning accuracy and short first time. SIM68RB module size 22.4*17*2.7mm, using SMT LCC package, the production process requirements are low, can be easily integrated into the customer's application products.
