JTAG Interface Board 1

JTAG Interface Board 1

The JTAG Interface board 1 (IB-1), is an adapter board that allows you to connect the Atmel AVR JTAG-ICE programmer to a Tag-Connect in-circuit debug cable (TC2050-IDC- NL). The Tag-connect cable is a great cable that allows JTAG connections in a compact space on your board without having to solder a connector. Tag-Connect is available on their website (http://www.tag-connect.com/TC2050- IDC). The cable comes in 0.1” spacing which is great for some programmers, but not for the 0.05” spacing of the JTAG-ICE. Our adapter board allows you to connect your existing JTAG-ICE to the Tag-Connect spring-loaded cable.

 

The cost of the adapter board is $19.95 (plus $4.50 S&H, domestic destinations only.) Included in the purchase are the schematic decal and PCB footprint for Altium users. These will be emailed to you.

SF-7 Current Sensor

SF-7 Current Sensor

The SF-7 is based on the Texas Instruments INA138 High-Side Measurement Current Shunt Monitor. It has a maximum input voltage of 36V and is designed to measure currents between 10mA and 500mA. It uses a 0.1-ohm sense resistor and has a transimpedance gain of 4V/A. An antialiasing filter of 15.4khz is placed after a unity gain buffer that feeds a Texas Instruments ADC121C027 12-bit analog to digital converter. There is one jumper that allows the user to select between three addresses. The ADC reference is connected to VDD so the resolution is based on the voltage applied to the device. It communicates using a 2-wire interface compatible with I2CTM which supports Standard (100kHz), Fast (400kHz), and High Speed (3.4MHz) Modes. It has an out of range alert flag readable as part of the conversion register.
When purchased, additional information will be emailed to you including a Bill of Materials, pdf Schematic, board and Microchip datasheets, Altium schematic, Altium schematic and PCB libraries.

SF-1 Temperature Sensor

SF-1 Temperature Sensor

The SF-1 is based on the Microchip TCN75 2-Wire Serial Temperature Sensor. It has a resolution of ±1°C from -40°C to +125°C.  The resolution can be set, by the user, to one of 4 selections from 0.5°C to 0.0625°C.  The input voltage can be between 2.7V and 5.5V.  It communicates using a 2-wire interface compatible with I2CTM.  There are three jumpers that allow the user to select the sensor communication address. Typical power consumption is 200 µA.
