play music, poor sound quality, noise1. Check whether ES8311 is poorly soldered or damaged.2. Is the speaker 8 ohms?3. The speaker pad is tinned
. Screen is distorted or no display is on the screen.1. Check whether ES8311 is poorly soldered and whether the BUSY pin of the screen holder is tinned.2. Check whether the capacitors in the next row of the screen holder are leaking or cracked.3. The capacitors in the screen drive circuit must withstand a voltage of more than 35V.
The radio is silent or the sound is low. Check whether the pins of the radio module are poorly soldered.Related

Ink screen/ESP32-WROOM-32D 4MB
supports up to 32G SD card, using Maozi's SdFat library
Mouse encoder and mouse button, super long life, scroll wheel design
3.5mm headphone jack, can be used alone as a headphone and as a radio antenna, can also use the USB charging port as an antenna
Audio playback uses ES8311+NS4150, limited by the size of the board, only provides mono
radio Use RDA5807M module
Use ultra-thin side-generating sound cavity speaker 3520, 8Ω
clock chip RX8010, temperature and humidity chip SHT30
The clock uses button power supply & lithium battery dual power supply design
Add USB & lithium battery switching circuit, audio is another set of power supply If the battery is not connected, the charging chip must be soldered to supply
power Battery limit size 34x50x 3mm, which is also the size used now. 303450
sleep current 0.015ma, i.e. 15ua,

Assembly Guide
The screen holder must be soldered in the correct position, otherwise it will affect
the assembly. Use 4 self-tapping M1.0X5 screws for the shell, and 2 self-tapping M1.0X5 screws for the button battery compartment.
The screen needs to be installed with a top block, first use double-sided tape to stick it to the PCB.
Use two AG0 button batteries in series, and pass the tinned copper wire through the shell to pad the battery (it is recommended to stack it thicker), and then pass it through the PCB. The positive pad of the button battery is soldered. Clock
