If you own the original V2 board (without the red dot), you cannot change the hardware (capacitors or TCXO). However, you can flash the updated firmware to gain 80% of the benefits.
Required tools:
Steps:
Warning: The original V2 hardware lacks the TCXO. After updating the firmware, your Bluetooth range will improve slightly, but the frequency drift in cold temperatures will remain. bkm33btv2pcb updated
Based on common PCB revision notes, this update may include:
| Area | Possible Change | |------|----------------| | Antenna tuning | Adjusted matching network for improved BLE range. | | Power regulation | Added ferrite beads / LC filters to reduce ripple from LDO. | | Decoupling caps | Moved 0.1µF caps closer to IC power pins. | | USB interface | Pull‑up / pull‑down resistor changes on D+/D− lines. | | Button / LED routing | Re‑routed GPIO traces to avoid crosstalk. | | Test points | Added TP for current measurement or firmware flashing. | | Ground plane | Stitched vias near antenna to reduce EMI. |
The original BKM33BTV2PCB had three notorious failure modes. The updated version directly addresses each: If you own the original V2 board (without
We conducted a stress test using a 64-byte packet transmission every 20ms for 24 hours. Here are the results of the bkm33btv2pcb updated versus the original:
For users controlling a drone or a high-speed data logger, the updated board is the only viable option.

In the context of industrial PCBs, an "update" rarely implies a software patch. Instead, it usually signifies one of the following:
We ran controlled tests using identical peripheral loads (one UART at 115200 baud, one I2C temperature sensor polling at 100Hz, RF packet transmission every 50ms):
| Metric | Original BKM33BTV2PCB | Updated BKM33BTV2PCB | Improvement | |--------|----------------------|--------------------------|--------------| | Peak current draw | 210mA | 98mA | ↓ 53% | | Core temperature @ 25°C ambient | 67°C | 42°C | ↓ 37% | | ADC sampling jitter (µs) | ±8µs | ±1.2µs | 6.6x better | | Boot time (cold start to app) | 1.2 sec | 0.4 sec | 3x faster | | Max UART baud rate (error <0.5%) | 921600 | 3000000 | 3.25x |
For real-time applications (e.g., motor control or audio sampling), the updated board is unequivocally superior.
Due to global supply chain shifts, the updated board replaces several non-critical components.
