jDrones News: jD-IOBoard v1.0 update
You had some problems on driving LED strips or something else?? Well no problems anymore.... We have seen people making all type of darlington/transistor and similar hacks to drive their LEDs, Sirens and so on but they all need a lot of hacking and they might not be suitable for long term solution.
We answered on this call and made fully Arduino compatible called jD-IOBoard that can run Single LEDs, LED Strips, Loudspeakers, Buzzers, Power switches and so on. It's upto your own imagination on what all you can control with this board.
So what does this board actually do?? It has fully Arduino compatible ATMEGA 328 MCU and Darlington array to driver high power outputs. Also I2C pins are exposed and same as many TTL level IO and Analog pins. As you can see from picture above.
Board has:
- 6 x High power outputs, max. 500mAh / 50 Volts
- 4 x Analog inputs (6 if you don't use I2C port)
- I2C port for controlling, listening I2C messages
- 6 x TTL level GPIO pins (8 if you don't use FTDI)
- 1 x FTDI port
3 high power outputs can also be controlled by PWM output while another 3 are just normal "On/Off" outputs
How those Arduino pinouts looks like:
Connecting LED's,Buzzers etc is really simple. Just use one of output pins on end of the board. Below you can see examples on how to connect LEDs or LED Strips on it.
Pictures does not give enough credit for how it works so we made small video to show just few examples on how to use it. There are many other ways to do it but this should give at least some idea what/how to run it. So have fun watching it.
Get yours from jDrones Store: jD-IOBoard and have a blink blink.
Ps. There are some nice features coming to this board shortly...

Cheers for that Jani. :) Makes life much easier.
Andie, If you have LED strips. Connect all +Plus wires from your LED strips together and then put directly to Battery +. LED Strip -GND cable goes to IOBoard output pins. This is shown already 3rd diagram picture in this post.
Here are latest pictures of V1.1 pinout and also differences between V1.0 and V1.1.
Main changes are on FrSky telemetry port area, now D5, D6, GND are next to each other for easier cabling. V1.0 had D7 between GND and D6 pins.
D7 has been moved to high power outputs and D2 has been moved from high power outputs back to TTL level outputs. D2 is an INTERRUPT pin so you can measure for example PWM pulses with that pin really easily. (There is example code in Arducodes repo)
Most important change is new GND pin next to +LOAD input pin. This used to be +5v pin on V1.0 but it was not never used but still BE CAREFUL not to mix V1.0 and V1.1. This way it's more convenient to have 2 pin cable coming from your secondary battery to power LED strips etc.
Differences between V1.0 & V1.1, Study carefully
Anybody else have a high load input and ground wiring diagram for v1.1 board? Looking at the back of the board it has ground under the high load pin.
Hi Jani, I have v1.1
Andie, do you have v1.0 or v1.1 of IOBoard??
Could someone let me know if the end pins on the light side are 12v and ground. It says GRND on the board but the diagram on the wiki says that pin is 5v. I've tried the new wiki but there doesn't appear to be anymore info there.
Jani,
I think they are fairly new, but I will give that a try. Thanks.
Ryan have you updated your FTDI drivers from FTDI website?? On somepoint there were problem with FTDI drivers and they corrupted bootloader with old Configurator. Win7 is now tested and it works.
I am also having an issue with the v1.1 boards (avrdude: stk500_getsync(): not in sync: resp=0x00). I have contacted jDrones support several weeks ago, but have not received an answer back.
I just bought some APM 2.5 FCs, JD IO Boards and Telemetry Distribution Boards. I also have some 3DR telemetry kits. Please post a new diagram on how to connect all of these parts. Thank you.
