And as you see there are three values for %-values to change color. I think that we aren't talking about the same. The 3 %-values are probably for the different LED colors (R, G, B). Quote
Lok24 Posted December 24, 2019 Posted December 24, 2019 (edited) The colors are obviously predefined, and you can enter %-values, as shown in the block. So the "plug"-function should deliver some numerical value to change the color accordingly. Edited December 24, 2019 by Lok24 Quote
Roman69 Posted December 25, 2019 Posted December 25, 2019 - Привет вам! Скажите мне, могу ли я подключить 8 AA 1.2 V к HUB 4.0? выход составляет 11,2 в при полной зарядке. Quote

Roman69 Posted December 26, 2019 Posted December 26, 2019 Hi! Tell me, can I connect 8 AA 1.2 V to HUB 4.0? the output is 11.2 V when fully charged. Quote
Lok24 Posted December 26, 2019 Posted December 26, 2019 The motor drivers in the hub (LB1836M) have a max voltage of 10.5 V as far as I know Quote
Roman69 Posted December 26, 2019 Posted December 26, 2019 Thanks! I will connect 12 AA 1.2 volts through the Converter and set the voltage to 10 volts. Quote
Lok24 Posted December 28, 2019 Posted December 28, 2019 (edited) Hi, some issues: 1.) Just tried to activate a WeDo Color Sensor on some Hubs: nothing The tilt sensor works.Is it just my sensor or something in the system? 2.) No technic Motor on move hub, neither Boost-App nor Powered Up-App ? 3.) Handheld connects only to one of me move hubs (both FW 2.0.00.0017), and pressing A+ moves motor C? Anyone there with similar probs? Edited December 28, 2019 by Lok24 Quote

Anyone there with similar probs? 1) I have no wedo sensor 2) I can confirm that. But I think that the problem already was there before the latest PUP App update and there was no firmware update for the Move hub with 3.0.0 3) My Move hub doesn't connect to my handheld Quote
Roman69 Posted December 28, 2019 Posted December 28, 2019 Tell me, how many amps can be applied to the hub? Quote
Philo Posted December 28, 2019 Posted December 28, 2019 22 minutes ago, Roman69 said: Tell me, how many amps can be applied to the hub? Motor driver inside hubs is current limited to a fairly low value (400mA continuous). So using 0.7/0.8 A per port is really safe. 1.5A for a pup hub, 3A for a C+ one. Quote

Technic motors (L and XL) are not working with the move hub in BrickController2 too, so it seems to be a hardware and/or firmware limitation. The medium motors (from the batmobile) are working with it though. Quote

I purchased the Hub and two motors (XL,L) on Bricklink. The Control+App is useless, there is no "Standalone"-Mode to run or configure the motors for an own model or MOC. The App is only useful If you have the Liebherr and all Motors are connected to the provided slots... Hello, see connection diagramm,in picture below, maybe this is usefull. Quote
AVCampos Posted January 3, 2020 Posted January 3, 2020 But aren't those resistors' values and the pins they're connected to meant to identify the kind of peripheral and thus how the hub handles it? Quote
Lok24 Posted January 3, 2020 Posted January 3, 2020 You can use the Powered Up-App to run technic motors on the technic hub or Smart hub. Quote

Please note that they have used an ordinary STM32 Microcontroller + TI Controller for wireless communication. It makes me wonder why the did not used something like https://www.st.com/en/microcontrollers-microprocessors/stm32wb-series.html Quote

Yes they are, but only for "dumb" motors (M-motor, train motor, LEDs). Control+ or Boost motors are identified through serial link protocol.

See https://philohome.com/wedo2reverse/connect.htm Hello, besides the fact what is the current output limitations of the iven LEGO Hubs, do you have any information /idea what is the maximum allowed current rating for wire , plug, socket contats , thanks in advance. I ask, because someone may have the idea to build an compatible Technic Hub on his own ;-) Marc Quote

Correct, just for the sake of clarity, quite the opposite. Top left - J10 - is for the CC2640R2F, the TI bluetooth controllerhttp://www.ti.com/lit/ds/symlink/cc2640r2f.pdfhttp://www.ti.com/lit/ug/swcu117h/swcu117h.pdf (for JTAG details) I did an attempt to understand it a bit more, see the schema. Hope it helps. I have no idea on the STM32 JTAG connector's pinout (J8). My 2 cents! Quote

(maybe they are dropdown linear regulator?) Ciao GanCann, accordingly with @Philo they are Conditionning chip for IO connectors pin 5/6. Exact function yet to be determined. Powered from +3.3V_CPU Thanks to some research I've found this post https://bricks.stackexchange.com/questions/10257/what-electronics-are-inside-the-lego-powered-up-hub where the author identifies the H25 chips as Dual buffer/line driver; 3-state CMOS level (one per channel, starting with the Powered-UP series) 74HC2G125https://assets.nexperia.com/documents/data-sheet/74HC_HCT2G125.pdf From this source: Both digital buffers and tri-state buffers can be used to provide voltage or current amplification driving much high loads such as relays, lamps or power transistors than with conventional logic gates. But a buffer can also be used to provide electrical isolation between two or more circuits. Hope it helps! Quote

To be honest, way less, as you identified the fuse on the wedo to be a 1.5A fuse.. :) so considering this and the board own consumption this is probably designed for a max of 0.6-0.7A per channel?)

Yes, but if you build your own controller you can used a much more capable motor driver... then physical limits of the connector are important to know ;) Quote
Lok24 Posted January 14, 2020 Posted January 14, 2020 (edited) Hi all, there are some issues that I can't explain, perhaps someone can confirm... Here is a very small program with the poweredUp App: Running perfect on technic hub and move hub On smart hub motor starts and then moves continuously with constant v, even when program is stopped with the red button. Often connection is lost after some seconds. Spooky. Edited January 14, 2020 by Lok24 Quote
