Change History#

This section describes the change history of this document and board. Document changes are not always a result of a board change. A board change will always result in a document change.

Document Change History#

Table 56 Document change history#
Rev	Changes	Date	By
0.0.1	Initial BeagleBadge documentation	August 2026	Deepak Khatri
0.0.2	All 25 schematic sheets embedded and annotated, board revision history added from schematic sheet 1	September 2026	Deepak Khatri

Board Changes#

The authoritative board revision history is printed on sheet 1 of the schematic, which is reproduced at Table of contents and revision history. It is summarised below. Also check the issues list in the BeagleBadge repository.

Table 57 Board revision history#
Rev	Date	Main modifications
Rev A	14 October 2025	Initial release.
V0.3	20 October 2025	Capacitor withstand voltage raised to 2x or higher. AND gate schematic symbol corrected. Switch control added to the power monitoring ADC. `RTC_PG` and PMIC circuit modified to reset the AM62L. Output capacitor of `TPS22965DSGR` marked DNI. eMMC circuit added. Wake-up signals `WAKEUP0`/`WAKEUP1` corrected. Tag-Connect changed to a SOIC16 bite. Button GPIOs moved to 3.3V I/O because they connect to the SOICbite. I2C signals left unpopulated for touchscreen compatibility.
V0.4	24 October 2025	`U9` replaced with 0R resistors to switch low power mode. Boot and Select functions merged onto one button. Up/Down/Left/Right buttons replaced with a joystick. `SPI1` used to connect `U42` (SPI to GPIO) and mikroBUS. Network identification descriptions corrected and extended. Some GPIO allocation adjusted.
V0.5	28 October 2025	Power supply selection added for the IMU. `U62` circuit modified to prevent its input floating. `EXT_WAKEUP0` added to pin 12 of `J29` (SOICbite).
V0.6	29 October 2025	`M23/GPIO0_43/3V3` used to reset the USB hub. `F22/GPIO0_29/PWM/3V3` used to drive the buzzer. RGB LED changed to a smaller package.
V0.7	5 November 2025	Sheet 8: `VDDS0` supply voltage corrected to 1.8V. Sheet 19: JTAG signals changed to 3.3V through a buffer. Sheet 24: the “Other GPIOs” pins changed to 1.8V.
V1.0	25 April 2026	Sheet 5: `R639` changed to an NTC, charging cutoff at 45 degrees C. `R341` changed to 2.4K, charging current reduced to 430mA. Sheet 6: final power mode set to `RTC ONLY + IO + DDR`, with `U6`, `U8`, `U10` and `U39` removed. Sheet 7: `U88` added and the USB hub power design reworked so that the 3.3V and 1.8V rails are powered only while Type-C is connected. Sheet 10: `U60` removed, USB hub now reset directly from a GPIO. Sheet 18: `U36` LoRa module removed, Wi-Fi power switch button added. Sheet 20: Power button added. `D24` replaced with `ESD0301L` and a 220nF capacitor added for ESD protection. Sheet 24: `J27` lost `AB9/RGMII2_RD0/1V8` and gained a sensor 3.3V pin. Sheet 25: eMMC marked DNP. Minor passive adjustments across the schematic.
V1.0	28 July 2026	`U36` to be mounted as required. PCB version number unchanged. This is the revision documented here.

Rev V1.0#

The production release. Schematic BeagleBadge_V1.0_SCH_260728.pdf dated 28 July 2026, board file BeagleBadge_V1.0_260826.brd dated 26 August 2026, on a 6-layer 1.6mm PCB.

Three decisions in this revision change what a user can expect from the board and are worth reading before you buy or design against it:

eMMC is not populated. The footprint is there. The device is not. See eMMC footprint.
The GPIO expansion pads are 1.8V, settled in V0.7. See GPIO expansion header.
Charging is limited to 430mA with a 45 degrees C NTC cutoff, which sets how quickly a BL-5C cell recharges. See Battery charging and power path.
