1 Product Features
1.1 Feature Highlights
• Features based on TC35 and in addition new or improved functions
• Largely HW- and SW compatible
• Same mounting concept
• Same size as TC35
• Same required peripherals
• PCB: single sided
• PCB: super slim
• GSC-antenna connector
• ZIF connector 40pin
• Extended AT commands for industry
• SIM Applikation Toolkit
• 7E1
• Dual band 900/1800 MHz
• GSM only
Significant difference:
The input voltage range has changed by the upper voltage limit:
• TC35: 3,3 V – 5,5 V
• TC35i: 3,3 V – 4,8 V
We recommend a operating voltage of 4,2 V.
Note:
New measurements (EMC, ...) have to be done for a migration TC35 / TC35i.
Furthermore the approval of the application has to be updated.
