Is it possible to add PSRAM or HyperRAM for the DA16200? What is needed to increase RAM in DA16200?
Thank you for a good question! DA16200 can't extend RAM. DA16400 (2.4G/5G dual-band) will support this, but development is on-hold.
fyi, QSPI RAM might be an option
for example 16Mb APS1604M-.... or or 64Mb APS6404L-...
