Serial Output

{ “a”:{ “max”:1.20, “min”:0.70, “avg”:0.95}, “v”:{ “max”:5.00, “min”:5.00, “avg”:5.00}, “mah”:0.01, “mwh”:0.04, “shunt”:0.07, “dp”:1.06, “dm”:1.08, “ram”:1420, “time”:24200}

A: - This consists of three parts. Max, Min, and Avg of current during the sample period. V: - Consists of max, min and avg voltage readings during the sample periodTotal miliamp hour measured since last boot or reset by command or button. Total miliwatt hour measured since last boot or reset by command or button. Shunt voltage (in mV) drop across the sense resistor which is used internally to calculate current. This is the voltage reading of the USB differential data lines D+ and D-. Could be used to figure out charge modes for various devices. Shows the current amount of free SRAM available in the microcontroller. Mostly for debugging but could be useful for anyone wanting to customize the firmware. In FW2.3+ this is disabled.Current time in milliseconds since power up or reset.

OLED Backpack: How to Update Firmware

Thu, 02 Mar 2017 23:23:02 -0800

There are two ways to update the firmware on the USB Tester OLED Backpack.

Wizkers.io - Easy to use and requires the Chrome browser. (currently a bug prevents this from working on Windows.)
Arduino IDE - Allows you to make your own code tweaks

Wizkers.io

Download the app from the Chrome web store.
Launch app and add the USB Tester under the instruments tab. At this point the USB Tester should be connected to the computer.
Select FriedCircuits OLED Backpack from the list and configure the correct port.
Click save and then click settings on the top right.
Select upgrade firmware.
Use get latest to download the current release. If you are trying out a beta release please down the HEX file manually and click select file.
Finally click upgrade firmware to flash the device.

USB Tester and Quickchargers

Sun, 17 Apr 2016 15:51:13 -0700

Most new phones use a new charging standard called quick charger which uses a higher voltage to provide the needed current to charge your phone at a faster rate. Because of this, the higher voltage will damage the USB Tester Backpack as it runs at 5V and has no regulation.

Fear not! You can still use it with a quick charger. It just needs a slight modification. The only change in operation will be for the OLED Backpack - it will need its own 5V USB power source. All you need to do is cut the solder jumper on the back side of the Backpack. The location is shown below.

1x Backpack PCB SMD Parts assembled
1x 128x64 OLED
2x 5pin Female Header

By default the solder jumper on the bottom is connected to allow shared power. This means that the device you are measuring will also power the backpack (Except for the VA Tester). It will not affect the measurements. If you want to have separate power you can use a blade to cut the trace between the two pads. This can be useful if you are measuring a battery for example.

Place the USB Tester

The easiest way to solder the headers is to place the USB Tester.

Thanks for supporting FriedCircuits with your purchase.

Depending on the options of your bundle, you will find the assembly and usage guides by clicking on the appropriate board below.

USB Tester

The base of the bundle: a breakout for probing USB devices.

OLED Backpack

Where the magic happens - graphic display, data logging, power usage.

VA Tester

Probe and use the Backpack with projects other than USB.

Acrylic Base

Protection from other metal objects, while looking official.

VA Tester Assembly

Sat, 20 Jun 2015 17:22:22 -0700

Parts

1x PCB
2x Screw Terminals
1x 14pin Male Header

VA Tester front

Step 1

Depending on your configuration you don’t need to solder all the headers. So skip that parts you don’t want.

Start with breaking the 14p header into 3 sections.

2x 5 pin
1x 2 pin (Already separate)
1x 4pin

Take the 4pin header and remove the middle two pins with pliers or you can just push it on and it will push the middle two out. Then holding one side with your finger you can solder from back.

USB_Tester20Blk

Included Parts:

1x PCB
16pin Male Header
1 2pin Jumper

The assembly is similar to the VA Tester, except only one pin to remove. Having the voltage pins being separated allows easy use of test clips and stops accidental placement of the jumper.

The new version of the USB Tester now has micro USB, more test points for regular DMM test probes and dual banana clips, and voltage test points are spread out. Same size and fits the same acrylic base How to use: Usage is the same as version 1.x but now you don’t have to worry about the banana leads touching on the back side. Here is a link to the usage guide of the 1.x series till we update for 2.0. /usb-tester/

Info: LED Matrix Master
Purchase: Tindie
Included: 1x PCB

1x 6p Right Angle Male Header
1x 5p Right Angle Female Header Solder Headers Facing the side with the IC the male header goes on the left for the FTDI and the female is on the right for connecting to LED Matrix Links. When soldering the female header make sure you hold it straight. What helps is to hold it and solder the middle pin. Then you can check and adjust as needed before soldering the rest. Once soldered its time to test it! If you are using it with the LED Matrix Links it should be pre-loaded with a test sketch. It should light up every LED on however many Matrix Links are connected. Just be carfull of power draw if you have many Matrix Links connected. In the Arduino IDE use board type Arduino Uno. More info and usage: /led-matrix/led-matrix-master/ “LED Matrix Master”

USB Tester OLED Backpack Description

Tue, 05 Nov 2013 10:55:51 -0800

Introducing the new USB Tester OLED Backpack! This is an add-on for the USB Tester which can be found here: https://tindie.com/shops/FriedCircuits/usb-tester/. Instead of having to connect your Digital Multi-Meter to the USB Tester you can attach this backpack and get the readout directly on the display. The backpack consists of two PCBs: the first PCB has the microcontroller with sensing circuits and the second contains the OLED display and driver. The OLED display is made by Adafruit Industries and mates directly to the USB Tester OLED Backpack. The left side of OLED display will show the instantaneous bus voltage, shunt voltage drop, device voltage, and current usage. The right side will display a short term graph of the last minute or so of current usage.

USB Tester and Phone Charging

Thu, 25 Jul 2013 21:32:43 -0700

One of the many uses of the USB Tester is to see how much current your phone uses while charging. Below is a picture of this setup if you would like to try it.

Aerial View

Connects to your phone via a Micro USB\iPhone cable to your device.
Connects to your computer or USB wall charger (If you don’t have a Mini USB cable you can use an adapter here).

If you would like to data log the phones current over time you can connect the upper USB connector to your computer as seen below.
