I am working on a design for a <3"x3" board to break out the Teensy 3.1/3.2 pins to individual or paired Molex SL latching connections, same as what Hansen sells as Latching Polarized connections. Similar to servo connections, where there are one or two signals, plus power and ground.)
Currently, the board is looking like it will have:
8 Digital I/O only lines,
12 Analog In or Digital I/O
2 or 3 Serial (notionally one RS232 and one TTL)
Trying to gauge interest among the community if this will be something they are looking for. Any requests, reply below. Plan is to release the board as Open Hardware, but because the connectors can get expensive, looking into bulk buys and selling kits.
Absolutely. We’ve used them before on robots and in other projects. Plus I don’t think I’ve seen a breakout or “shield” for the Teensy before.
If anyone doesn’t know what a “Teensy 3.2” is, it’s basically an Arduino with way more processing power, I/O, small footprint (more like an Arduino pro mini), and low price. Plus you program it with the Arduino IDE and any sketches that run on the Arduino run on this.
3 pin for single channel, 4 pin for I2C or paired channels (think encoders) and 7 pin for SPI. I love these connectors - shrouded from accidental contact, mechanically keyed, latching against vibration, rated up to 3A each (perfect for 22AWG 2A circuits).
Bonus: Use the same series for locking inline connectors:
Male Housing: 3 Pin; 4 Pin; 7 Pin
Male Wire Crimp Connector: Digikey
What do you use a Teensy in? Like, this isn’t a “Gauging interest” question, I would really like to know what other teams are doing with this sort of thing (since my team really isn’t using it at all)
I’ve programmed a Teensy for 3 things. One was as an example for my son to modify and extend for a senior design project (a home monitoring system). The second was a USB HID for arbitrary button inputs, with the beginnings of support for a rotary-encoder-based control knob. Finally, with an audio output peripheral as a museum exhibit controller that waits for a button to be pressed then plays a message and enables a motor to spin a turntable.
I also planned a programmable thermostat, but I could never get the built-in temperature sensor to give me reasonable data, and I wasn’t motivated enough to connect an external sensor.
Appreciate the interest, but the breakout board is not ready yet. When we tried using it during the season, the outputs we tried where barely getting above ground. (read: major electrical error somewhere)
As I get a chance I will work over the summer on this.
Quick Status Update:
Just redid the entire board in 4 layers. Previous 2 layer board had a lot of vias, and I think they were harming the signals. Also removed the ground plane that meandered everywhere, as I suspect that was causing a lot of coupling error.
Fingers crossed Will let everyone know how it goes!
