Throw Away PIC??
TAP-28 isn't "yet-another-me-too-development board" for PIC 18F-series 28-pin microcontrollers; it's an application board
with a dramatic difference - TAP-28 is so
inexpensive that it can be dedicated to a project without so much as a second thought. With prices starting at $8.33 (bare), it's literally a throw-away
Price isn't everything, though. TAP-28 is a workhorse, exposing the I/O you need for even the most port-intensive applications. Designed from the ground up for embedding in both one-off and low-volume projects, TAP-28 ditches the bling and the fluff to deliver a robust, app-ready, developer-friendly solution. If it's on TAP-28, it's there because it helps jumpstart application development. Period. No frills, no marketing-department-added "features" that look great on a checklist (but will never get used in the real world), no bullshit - just the capabilities of over 30 popular PIC microcontrollers, delivered in a convenient package.
The TAP-28 Rev. A boards are complete. All orders will be filled with the new boards.
- Support for most 28-pin PIC 18F-series microcontrollers.
- Reset switch
- Four LEDs and two general-purpose switches, each easily connected to the circuit with solder jumpers.
- Three six-pin connectors, each supporting GPIO (power, ground, port pins)
- ICSP connector - for use with PICkit 2, PICkit 3 or other programmers.
- UART connector - for use with PICkit 2 UART Tool, external RS-232 level-shifters, or third-party UART-USB interfaces.
- I2C/SPI connector - supports the PICkit Serial Analyzer convention. Pull-up resistors may be effortlessly enabled with solder jumpers as needed for I2C/SPI or other applications.
- Two software-configurable 3-pin ADC input/GPIO connectors, each with power, ground and a single port pin.
- Two 3-pin PWM/servo/general-purpose I/O connectors. Servos plug in directly. PWM or general-purpose I/O easily connected with power, ground and 1 port pin available.
- All port pins are available via header connectors for prototyping on a breadboard or for adding components using a daughterboard.
- Power via your choice of USB connector, bi-pin terminal strip (either may be installed) or connection at any of the header or six-pin connectors strips (i.e., powered by PICkit programmer or UART-USB converter).
What the TAP-28 Doesn't Include:
- MAX-232 lever shifter - nice during development but usually not needed for applications, so it's been designed out to reduce board cost.
- On-board voltage regulator - applications are frequently powered by USB connection, a regulated wall wart or directly from battery, so the board features no regulator to reduce cost.
TAP-28 boards are supplied as bare boards to allow customization by the user. Boards are high quality double-sided boards featuring through-hole construction, with top silk-screen and solder mask on both sides.
