Best Unit Option
Hello
I looking for the best unit options to do the following tasks.
- control or activate a solenoid (Relay Unit I think)
- read from a 9 pin serial port (RS485 to TTL)
if there are any other or better options I would like to hear them
thanks

RE: Servo Kit 180 connection
I have been able to get it working with the correct wiring using the grove port in a Core Basic Gray unit.
No I will start to use the io pins in the bottom of the unit so I can use the grove port for other things.
thanks for all your assistance.

RE: Servo Kit 180 connection
@ajb2k3 When the servo is attached and then plugged in, it does not start. When the servo is removed and then plugged in it starts..

RE: Servo Kit 180 connection
@teastain Thanks for the info. I hope you got something out of this adventure :). The StickC does not have a battery. I'll try with the Core Grey I have, it has a battery and see I can get it to work with the pins and not the Grove.
It does seem odd though.
thanks again
cheers Kyle

Servo Kit 180 connection
Hi,
I'm trying to connect a Servo Kit 180 to a M5StickC. However when I try the Stick shuts down when I connect the red pin.
See images below.
Do I need a separate connector or are the pins mixed up.

Sending file to server urequests
Best method for sending large sets of data back to api as a file.
I have tried urequests and the post does not like the keyword files.
does anyone have a method they would like to share.
thanks

RE: UHF RFID Unit (JRD4035) on M5Core2
Not sure if this will help.
I made a quick reader based on a [project I'm working on this also works on m5Paper as well it's nothing complex simple read and display, this is on a Basic Core unit
A quick video showing it working
https://youtu.be/qvtr6Vy-HwYThe Tags I use are these ones
make sure the port is correct otherwise the bytes out of range error pops up
I hope it helpsfrom m5stack import * from m5ui import * from uiflow import * import unit setScreenColor(0x222222) uhf_rfid_0 = unit.get(unit.UHF_RFID, unit.PORTA) uhf_rfid_0.set_region(uhf_rfid_0.REGIN_US) uhf_rfid_0.automatic_freq_hopping(0xFF) uhf_rfid_0.set_channel_freq(924.25) epc_bool = 0 uhf_rfid_0.set_select_mode(0x01) label0 = M5TextBox(128, 59, "Tag #", lcd.FONT_Default, 0xFFFFFF, rotate=0) label1 = M5TextBox(22, 106, "waiting ...

RE: UHF-RFID M5Stack Current and Power consumption
I have noticed it drains the battery of the M5Paper quite quickly. I have not tested that specifically as it was not a requirement for my project. The range is quite good at 50-70 cm.
I think there is a way to change the power and read strength, though I have not investigated too deeply. I am using other methods to alter read time. When I get to a stable point I will refine some more.
