The SIEMENS TC35 is a standard AT commands Based GSM module, you can easily apply it with your own embedded system to creat a GSM wireless based data transfer module .Support Arduino!
The SIEMENS TC35 Module is AT Command - controlled gsm modem, via Serial Port (RS232/TTL communication).
Program source code would be provided so that buyers can use the module easily and get familiar with the module quickly.
Common applications are (sending/receiving) SMS control, phone calling.
This is "resistance substitution box" good low-cost alternative solution, can flexible and quick setting resistance range from 1R to 9999999R, step accuracy 1R. for educational experiments, electronic engineering design or test trimming are excellent applications.
Design based on “resistors series” theorem.
1/2 watt tolerance +/-1% SMD resistors.
Screw terminal block easy to connect wires.
High quality FR4 glass fiber PCB.
With spare parts 10 pieces jumper caps (on board 7 pieces, total 17 pieces).
