RN2903 RN2903 Module Errata and Data Sheet Clarification The RN2903 module that you have received conforms functionally to the current Device Data Sheet (50002390B) and the “RN2903 LoRa® Technology Module Command Reference User’s Guide” (DS40001811A), except for the anomalies described in this document. The module firmware version can be identified by issuing a System Get Version command (sys get ver). For more information, refer to the “RN2903 LoRa® Technology Module Command Reference User's Guide” (DS40001811). The module firmware issues are summarized in Table 1. The errata described in this document will be addressed in future revisions of the RN2903 module. Note: This document summarizes module firmware issues for the current, released to production firmware (0.9.5). Past module firmware issues are documented in Appendix A. Current Firmware Features and Fixes of the “RN2903 LoRa® Technology Module Command Reference User’s Guide” (DS40001811).

Past module firmware issues are documented in Appendix A. Current Firmware Features and Fixes of the “RN2903 LoRa® Technology Module Command Reference User's Guide” (40001811). 1. Issue: Data Sheet Clarifications There are no typographic corrections and clarifications to be noted for the latest version of the Device Data Sheet (50002390B). Sleep current out of specification Sleep mode current may draw 100-150 µA. Work around There is no work around for this issue. This issue will be addressed in a future firmware revision. Affected Firmware Revisions 0.9.5 X 2. Issue: GPIO pins default to ground Upon initial power on of the module, the GPIO pins default to ground. Depending on the use of the GPIO pin, this may cause concern with connections to the GPIO pin that can cause a short to ground until the GPIO pin has been configured by the user. Work around Place a current limiting resister in series with the GPIO connection. This issue will be addressed in a future firmware revision.

DS80000693A-page 3 RN2903 NOTES: DS80000693A-page 4 2016 Microchip Technology Inc. Note the following details of the code protection feature on Microchip devices: • Microchip products meet the specification contained in their particular Microchip Data Sheet. • Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. • There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. • Microchip is willing to work with the customer who is concerned about the integrity of their code. • Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.” Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
