a dwarf board for 40-pin PIC chips
The DB057 board hosts a 40-pin PIC chip and an 7805-based 5V power supply. The PIC pins and the 5V are accessible on four Dwarf Bus connectors, and on wire cups. The board has a green power LED, and a red LED that connected to RA4. It has pickit2 / pickit3 / Wisp648 style connectors for In-Circuit program, and room on the PCB for ICD2 / ICD3 and old-style Wisp648 connectors, For USB PICs like the 18F4455 and 18F4550 the board contains an USB connector, and a switch to select between activating abootloader or the application program. More details can be found in the DB057 manual. A ZIF socket can be placed on the PCB, but teh handle will be very close to some components (R2, R3, R7, power and blink LEds) when all componets are fitted.
The DB057 is availabe as bare PCB (http://www.voti.nl/shop/p/DB057-PCB.html), or as a kit (http://www.voti.nl/shop/p/DB057-Kit.html). It can be assembled either for USB PICs or for on-USB PICs. The kit contais the components for both options. The kit does NOT contain a PIC or a crystal. Choose one yourself, suited to your application.
The bootloader .hex file, the PC application, and all sources can be found below. It is a slightly modified version of the Diolan bootloader. The bootloader is provided under GPL license. The command for downlading using the bootloader can be found in the DB057 manual.
