otter-iron's Introduction

Otter-Iron

Replacement PCB for TS100, adds USB-C PD to every hacker's favourite tool!

Hardware v2.4 is released, changelog: you don't need to solder the tip connector anymore, software v0.6 is released!

Features:

You can solder!
Temperature can be adjusted via buttons
USB-PD requests highest voltage
Display shows set-temperature, temperature, input-voltage and power applied
Saves last set-temperature
Designed by an Otter chirps :3

Ordering and assembly instructions

The BOM can be found at KiCAD/Otter-Iron/production/kitspace_bom.csv. Most parts are generic parts, which can be ordered and assembled regularly. However, the display and tip-holders need special attention. The PCB has to be ordered with a thickness of 1mm (1.6mm works too, but 1mm has a better fit).

Known hardware issues/notes

Note: C19 and C20 changed from 100nF to 1µF in the last revision, please make sure to populate 1µF!
Please add a pullup to the displays reset if the display does not work. See image below:

Tip-Holders / mechanical parts

The original tip-holders are custom made thus it is not possible to buy them, if you already have a TS100 it is highly recommended to recycle those. They can be unscrewed, cut to size and soldered/screwed onto the Otter-Iron. This is the preferred option!

If you don't own a TS100 you can buy one from miniware (price ranges from 35$ to 45$) and harvest the parts (as well as the casing and tip!).

You can also buy the littlefuse fuseholders mentioned in the BOM. Those however have a very bad fit, you have to bend them and add a little solder notch, otherwise you may destroy your tips. In addition to this solution you also need to buy a spare case+tip which is ~25-35$, this is the least preferred option.

Display

The display can be bought from ~~LCSC~~ note: Do not buy displays from LCSC, they seem to be faulty! or Aliexpress, I haven't found it at Mouser yet (Maybe its this display?). It is the last part to be assembled, it is soldered on the back of the PCB facing the PCB and the tip-end.

Flashing

To flash the Otter-Iron short the DFU-jumper shown in the image below while plugging it into your computer. This will put the iron into DFU mode allowing you to flash it via DFU/USB.

If you already have ad firmware >= v0.2 flashed, you can press both buttons while plugging in to enter DFU mode.

Run this command to flash the downloaded binary.

$ dfu-util -a 0 -s 0x08000000:leave -D firmware.bin

otter-iron's Issues

Not an issue, but a question!

Can it be used to accept Weller RT tips by just changing the hot tip socket?

thank you

Minor layout issue with tagconnect header

Hey, this is not a major concern but you might want to fix it anyway - the tagconnect spec says everything between the centers of the pads is a keepout zone - you have a trace and a groundplane in that area. Seems the trace can easily be routed around along the board edge and the groundplane doesn't need to extend there.

Accelerometer planned?

First of all Great Project! I really love what you´re doing here. This is exactly what I´ve been searching for!
But on the original TS100 there is an accelerometer built in to put the device to sleep and wake it up again with the motion data. I really like this feature. So my question is, if it´s planned to implement this feature in the Otter-Iron?

Anyway I´m trying to rebuild the current PCB design and would like to give some support on the firmware.

TS100

Hi,
You designed a great PCB! I have some ideas to discuss with you.

Document different versions

Could you please document the different versions of the PCB? I see there is Otter-Iron, Otter-Iron_Devkit, and Otter-Iron_Portable. Maybe just a readme with a quick description, although pictures would be nice.

Adding barrel jack to Otter-Iron

Hi there, very impressive work. Bravo Jan!

I noticed on the to-do list, there was barrel jack. I'm wondering what's the status of it. Thank you!

Wireless Otter-Iron???

Could the Otter-Iron be powered by an integrated lithium battery?
I would love to be able to loose the wires for those small jobs not requiring the full 65w of power.
One could 3d print or machine a new enclosure with room for the battery

Adding in a boost for full power

For future revisions, perhaps you could consider integrating in a boost converter to supply 24V to the heating element, such that the full 65W of power can be used. Perhaps the space freed by the barrel jack can be used for this.

Add footprints for original tip-holders

Add footprints for the original tip-holders so that they don't have to be soldered on.

Sold on Tindie?

Any chance you'll sell these mainboards on Tindie or another similar storefront? I'd love USB-PD on my TS100 but I lack the ability to do fine pitched SMD soldering.

jlcpcb SMT assembly not working

after uploading the newest v2.3 gerber files provided by you to JLCPCB.com the smt assembly option is greyed out and telling me that only certain boards (1.0-1.6mm thickness, green soldermask, etc. ) are allowed for assembly, all of which are correctly selected.
Re-exporting the gerbers did not help, although interestingly enough, the X2 gerber files do seem to work.
FWIW I was able to select SMT assembly for a different 4-layer board designed in KiCAD a few days ago, which makes this issue even more confusing to me.

Great work btw, hope to have this on the way soon! 👍
