Part Number: TMAG5170
Usage scenario: The TMAG5170 sensor board and ESP32‑C6 board are connected via approximately 10 cm ordinary wires. When a magnet with a magnetic‑field strength of about 60 mT is brought close to and moved away from the sensor standalone, magnetic‑field variations can be detected by the sensor. Overshoot is observed on the clock signal during tests, which is improved by adding a series‑connected 33 Ω resistor.
It is a 2‑layer PCB as shown in the figure below. Is the PCB layout unreasonable?
With the sensor board mounted between two magnets, the SPI SCLK is pulled down to around 1 V. No output is present on SPI MISO, whereas MOSI and CS waveforms look normal. See the figure below for the clock signal.
