 I received the following email from Swiss Micros in 8th March 2024 explaining a hardware change that's required to early production units to ensure correct operation with the latest firmware, which allows the processing speed to increase when powered via USB (as per the DM41X and DM42). I received the following email from Swiss Micros in 8th March 2024 explaining a hardware change that's required to early production units to ensure correct operation with the latest firmware, which allows the processing speed to increase when powered via USB (as per the DM41X and DM42).

 I find the DM32 plenty fast enough running on batteries, so I'm not necessarily going to be plugging it it to boost its performance **but** I do want to stay up to date with firmware changes and don't want to risk any problems, so I've ordered the replacement SMD resistor and plan to swap it myself. I find the DM32 plenty fast enough running on batteries, so I'm not necessarily going to be plugging it it to boost its performance **but** I do want to stay up to date with firmware changes and don't want to risk any problems, so I've ordered the replacement SMD resistor and plan to swap it myself.
  
  
 +** update 24/01/26 ** - I //think// I did the swap.... after receiving the new resistor, not sure of the date.... I'm fairly sure I did, anyway!
