BasicX-24 Versions Changes
The BX-24p has been replace by the new RoHS compliant BX-24p-u. The -u is 100% hardware and software compatible with BX-24p and features the following Improvements/Changes:
Current Version: BX-24p-u
Improvements:  
Changed to comply with RoHS requirements
On-Board voltage regulator upgraded to 0.5%
Added voltage good signal from regulator to b1
Changes:
Changed PCB board color from black to blue
Swapped on-chip RED and Greeen LED positions
BasicX-24p-u Errata:
None

** Max input voltage based on I/O pin loads. Regulator output 5v +/- 5%
BasicX-24p Errata:
1. The current run of BX-24p chips has their surface mount LEDs switched. I.e. Green is now Red and Red is Green. This will be corrected in the next batch of chips
2. The BX-24p does not work with the Large Green BasicX Development Station. The board will need to be modified to remove resistors strapping the atn and reset lines. More information to follow.
3. Any strapping or loading of the Atn (pin 3) or Reset (pin 22) pins may interfere with or prevent downloads. Remove any strapping resistors or loads from these pins to correct the problem.
