A useful test development PIC16F877 circuit pcb printed circuit board design was quite nice small in size but has a lot of features. Serial RS232 connection, sensors, servos, PWM, I2C connector and so on. Experiment card with eagle schematics and PCB files are prepared. In addition, “the PIC Tutorial Programming” free ebook called shared.

Development, Experiment Circuits Atmel AT89C51RB2 AT89C5131A
Atmel AT89C51-series microcontrollers for RB2 and AT89C5131A summer programs that try to experiment with a variety of cards for AT89C51-RB-2, which carries the same features as the circuit usb-aided circuit instead of just usb rs232 connection. All circuits prepared with eagle pcb’s schema files and material lists.
Atmel AT89C5131A-USB: 4 buttons (cut), 8 LED display, LCD-Display, 2 × 16, 8-bit analog-to-digital converter, additional hardware connections to the pins, SPI interface, RS-232 communication interface, USB Port connection
