Works as expected
No issues with connectivity. The colon separator is controllable which is a nice touch for clock applications. Shipping was fast.

Good value, clear digits
Solid build quality. The soldering on the header pins was clean. Only minor issue is that the datasheet link was broken, but standard TM1650 code works fine.

Reliable component
I've bought three of these now for different sensor readouts. They are consistent in brightness and color. Easy to stack headers if needed.

Great for learning I2C
Bought this for a university project. It's very straightforward to wire up to an ESP32. The display is bright and the refresh rate has no flicker.

Compact and Bright
Exactly what I needed for a temperature monitor. The footprint is small enough to fit into tight enclosures. Highly recommended for hobbyists.

Perfect for Arduino Clock Projects
This module worked flawlessly with my Arduino Uno. The I2C library is easy to find and implement. Brightness is excellent even in daylight.
Q: Is the decimal point on each digit individually controllable?
A: Yes, the TM1650 driver allows individual control of the decimal point on each of the four digits, giving you full flexibility for displaying numbers or units.
Q: Can I drive this directly from a 3.3V ESP32 without level shifters?
A: Yes, the TM1650 chip operates comfortably within the 3.3V to 5V range, so it is fully compatible with 3.3V logic boards like the ESP32 and ESP8266 without needing level converters.
Q: What is the maximum current draw for all segments lit?
A: When all segments are lit at maximum brightness, the module typically draws around 60-70mA. We recommend ensuring your power supply can handle this load if driving multiple modules.
Q: Does this module come with the header pins pre-soldered?
A: No, the module comes with a separate 4-pin header strip that you need to solder yourself. This allows for flexibility in mounting orientation.
Q: Is there a specific Arduino library required for the TM1650?
A: Yes, you can use popular libraries like 'TM1650' by Avishay Orpaz or 'SevenSegmentDisplay' available in the Arduino Library Manager. Many examples are included with these libraries.
