Thank you for your support of our products. If you have any technical problems in the process of using, we will help you solve them as soon as possible.
JaneYu Hi! Do you guys know the max volts/ amps for the beetle? Thanks in advance!
JaneYu What is the output voltage on the digital pins?
JaneYu Hi abhay,
There are several output modes for the Digital pins, such as HIGH、LOW、PWM. If your code is digitalWrite(PIN, HIGH), then the corresponding PIN will output 5V voltage
Is it possible to control the Blue LED on the board. I see it's mapped to D13, but I don't see access to that PIN through the pins_arduino.h for this board.
JaneYu Hi Ryan,
it's possible to control the LED on the board, you just control it just like an Arduino. Would you please elaborate how are you trying to control it exactly? Have you tried the example code from the Arduino IDE?
When only connect USB power is supplied, is the pin "+" 5v?
JaneYu Yes, "+" gives exactly 5V
which pins on the board are pwn outputs? I have been looking for this info for the longest time
JaneYu Shouldn't the beetle start performing the sketch on power on?
Everything works fine as long as I upload the sketch via usb and don't disconnect. When I power up the beetle afterward the sketch doesn't start.
JaneYu Could you show me how do you power on beetle by pictures or screenshots?
Which pads on beetle can I use for Interrupts? Leonardo can do it on 0, 1, 2, 3 and 7. As fas as I can see, none of these are available on the pads on the beetle ...
JaneYu I wish I had seen this before ordering a bunch! NO INT pins available for a controller board ?? really ?? that seriously limits what it can be used for. The "Size Limitation" argument isn't a valid excuse IMO...more like an oversight. They CHOSE to bring out D9,10, 11...none of which have are interrupt pin...they could have brought out AT LEAST ONE of the interrupt pins...D-0,1,2,3, or 7 instead of the 9 or 10 or 11. Beetle was a nice idea and great size..but without external interrupts it's practical uses are extremely limited.
yeah, the wiki has more detailed information on each pin.https://www.dfrobot.com/wiki/index....
JaneYu Is there a dxf file available for the Beetle? Or a dimensioned drawing showing pin locations?
JaneYu I've connected two 3v ** batteries to run my beetle. That's 6v. Its working fine to power a neopixel ring. However, I've read in the instructions that 6v would be bad. Can you tell me if this is OK?
JaneYu Thanks. I perhaps didn't quite ask the right question so I will try this way: do the pins A0, A1, A2 and + have a pitch of 5.08mm? Also is the centre to centre distance between A0 and D9 = 16mm? I am creating a small shield for the Analog and Digital, gnd and +.
JaneYu I found the datasheet, but am unable to find the part in Eagle. Is there anything I can replace the PGB component with?
JaneYu Thanks so much! A few more questions:
What are the ports on USB1? Do 1+, M2, 3, 4, 5, 6 correspond to VBUS, D-, D+, ID, GND, SHIELD?
Also, are the PGB101603 equivalent to transient voltage suppression diodes with a value? If so, what is that value?
JaneYu Depends on what kind of sound you want to play, basically, you need a beetle, buzzer, LED, you can read about how to control these three elements and then put the functions together
JaneYu Hello,
I want to buy 10 Beetle boards, and chain them all using the I2C protocol.
To each Beetle board i will connect a potentiometer.
The first beetle will be connected to a pc.
The goal is to have a program in witch the user will write the number of the potentiometer/board (by the order they are chained) and the answer will be the resistor value.
1. To connect the first Beetle board to a PC, can i do it via the mini-usb that is on borad, or do i have to use I2C-USM module (or something like that) ?
2. How many Beetle Board can i chain to each other ?
Thank you for the help !
JaneYu If I under stand write, you want to transfer 10 potentiometers' value to your Arduino serial monitor through I2C (of course, the one connect to PC is using serial). You don't need to use an I2C-USB module, the Beetle connected to PC could be seen as the "data transmission", you can connect all Beetles' SDA together and SCL together, through different address, you can connect a lot of Beetles through I2C
