mjbots.com had a week long run where we were completely out of fdcanusbs, which meant that we were also out of all development kits too. Well, a production run just came in:
That’s a lot of enclosures…
So now we’ve got everything back in stock once again!
It seems like all the posts I’m writing these days are for new products! Here’s the pi3hat r4.4:
There are two changes from the previous r4.2. First, it now supports voltage inputs up to 44V. Second, in support of future upgrades, the 5th CAN-FD port has been upgraded to support 8Mbps, but downgraded to no longer have a wide common mode voltage range.
THUS, IT IS NOT SAFE TO CONNECT THE CAN-FD PORT ON THE pi3hat r4.4 TO A power_dist r3.X BOARD.
I’d like to introduce the qdd100 beta 2!
This is the newest version of a quasi-direct-drive servo from mjbots. It has a sleek new look, and improved performance all around:
| Beta 1 | Beta 2 | |
|---|---|---|
| Peak Torque | 12.5 Nm | 16 Nm |
| Backlash | +- 0.2 degrees | +- 0.1 degrees |
| Voltage Range | 10-34V | 10-44V |
| Mass | 470g | 475g |
Comparison from beta 1 to the new beta 2
Additionally, the M3 mounting holes are now 3mm deep instead of the previous 2mm, which gives more flexibility when designing mounts.
