This is dev.board based on STM32F103R microprocessor. Pin compatible with Arduino platform. For use with Arduino IDE use software from Maple project.

I use ATmega644P and need both UART. This modified loader use any 3 I/O line (RX, TX, LED) for load code from Arduino IDE. Test with ATmega644P (internal RC 8MHz), 38400 baud rates. PC5 = TX line, PC4 = RX line. LED on PB1.

Many publications say about use multi SIM in mobile phones. Very popular Silver cards SIM (and other). SIM holder and SIM is one of lagest element in GSM/GPS trackers. Roundsolutions use ST chip to implement SIM on chip on new mini tracker project. As i know from publications multi SIM cards build on PIC16F876 with 8/32KB EEPROM. I decide implement SIMonChip technology on AVR ATmega168 microprocessor. On of big problem in this project - how to know IMSI and Ki codes. But if you a legal mobile customer you can write request to mobile operator and know this codes (or crack it as describe on kiscan...

This USB adapter can communicate with other TR24A in char-to-char or packet mode. Add second TR24 to full-duplex communication (with a little changes). #include <TR24.h> // Arduino 0015 // Teensyduino 0.4 // TR24 library 0.1 // Build on AT90USB162 with TR24A radio module int TR24_CHANNEL = 6 ; // Default TR24 channel int LED = 4 ; // PD4 - LED connected to digital pin 4 char TR24Buffer [ 64 ]; char USBBuffer [ 64 ]; void setup () { Serial . begin ( 19200 ); pinMode ( LED , OUTPUT ); LEDOFF (); TR24 . begin ( TR24_CHANNEL ); } void loop () { char * ptr ; byte error ; // Blink 0.2 seconds interval...
