FAQ
Q1: Is TFmini-S available with 3.3V or other power supply voltage?
A1: Sorry, it is not available for the time being. The Standard power supply of TFmini-S is 5V±0.1V. If you have any further requirement, please contact our sales person to consult a customization design matter.

Q2: TFmini-S will heat up after operating for a while. Is it broken?
A2: This is the normal operating condition of the product. The temperature of the chip and circuit board will slightly up after a continuous operation, which is a normal case.

Q3: Can TFmini-S be connected with Arduino or Raspberry Pi for use?
A3: Yes, it can. TFmini-S adopts serial communication protocol so that it can connect to any control board supporting serial port communication.

Q:Hello, the manual helped me to understand a lot, but i have one question: how i calculate the checksum, if the checksum is over 265(for exampel I would to set a frame rate of 250hz) thank you for the fast help. ich love this device and i will give a good appraisal.
A: This is hexadecimal, if the checksum is over 265, you just need the lower 8 bits.

Q: I have the TFmini-S.
I've read the manual and read it again and I still don't understand this part:
0--standard data
mode
1--I/O,near high
and far low
2--I/O,near low
and far high
Can you expand at all?
A: 0 Standard mode is the factory default mode, it means continuous output mode
1 and 2 are both high and low level output modes. For example, if the threshold is set to 5m, then mode 1 means if output below 5m is high level , above 5m is low level; mode2 means if output below 5m is low level , above 5m is high level

Q: Has anyone adapted this for use under water ? I was thinking if encapsulation in acrylic and seeing if it could distance underwater.
A: This lidar sensor can not work underwater.
