We already had a good result in Feburary but throughout 2022, we have been refining circuits of qNinja and qNinja Lite to make them simpler, easier to be built and more sensitive. Now it’s done! We will push latest designs to GitHub soon and calculate final parts price later. We convince that qNinja Lite 1×8 …
We have spent these months to make circuits simpler. Here is the successful result. These changes not only reduce manufacturing price but also increase a robustness to survive chip crisis. Removed demodulator ADA2200 Removed -1V regulator TPS63710 Changed ADC from ADS1219 to NAU7802 (DIP or SMD) Changed LED driver from PCA9955+MCP4551 to TLC5929 We will assemble latest board and pick up best photodiodes. That …
Just ordered qNinjaLite:batch2/main with updates to reduce parts price. BOM will be updated later. Removed pricy and discontinued demodulator ADA2200 Adhoc FFC connector to choose best photodiodes. We already picked PDB-C152SM but other ones made by a company named OSRAM looks better and cheaper. All of their candidates are already soldered onto optical unit of …
