USB 8bit Interface Board
Posted on Monday, November 10, 2008   •   Category: USB Circuts


This is a USB (universal serial bus ) interface board which can be used to connect 8 (parallel) data lines to the USB. The interface comes with a small internal FIFO (384 byte Tx, 128 bytes Rx) and 4 handshake lines which make it suitable for interfacing microcontroller designs to the USB. It can, also be used as simple 8bit IO when the so-called “bitbang mode” is enabled. Note. however, that in this mode, the bits will not come out in a constant bitrate but in chunks of 64 bytes with specified baud rate followed by a delay.

Build Accurate LC Meter and start making your own coils and inductors. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils. LC Meter can measure inductances starting from 10nH - 1000nH, 1uH - 1000uH, 1mH - 100mH and capacitances from 0.1pF up to 900nF. The circuit includes an auto ranging and reset function to make sure the readings are as accurate as possible ... [more]
