Xhdata D808 Schematic Extra Quality (2026)

: The Si4735 DSP chip is the heart of the radio, handling almost all tuning and filtering functions.

There are anecdotal reports of the D-808 getting hot during charging. A clear schematic would show the topology of the TP4056 (or clone) charging circuit, allowing users to verify the charge current resistor (Rprog) and safely install larger heatsinks or swap to higher-quality 18650 cells. xhdata d808 schematic extra quality
