AFRC WE25A/WM1621 MINI Programmable Brushless Power Kit
For 1/24 1/18 MINI RC Crawler Axial SCX24 TRX4M RC Car Upgrade


4. After the software is opened:
1) Select the correct COM port.
2) Select Direct Connect.
3) Click the Connect button.
4) Click the M1 window to connect. If the connection fails, please restart the software, turn the ESC on and off once, and then click Connect again.

1. Reverse Rotation: Toggle motor direction (forward/reverse).
2. Complementary PWM: Enhances starting torque in complementary mode.
3. Variable PWM: Auto/manual PWM mode selection.
4. Bi-directional (fwd/rv): For cars/tracked vehicles (throttle midpoint = stop).
5. Stuck Rotor Protection: Disabled for crawlers.
6. Brake On Stop:Maintains braking when stationary.
7. Stall Protection:Required for crawlers – prevents jerking in slow-speed modes.
8. Sinusoidal Startup: Optimized for crawler mode.
9. 30 ms Telemetry:Enables Kiss telemetry output (30ms intervals).
10. Use Hall Sensors:Currently unavailable.
11. Timing Advance: Adjusts motor commutation angle (higher = faster but hotter). 1
12. Motor KV:Sets approximate KV value to limit throttle range.
13. Motor Poles:Configures pole count for sinusoidal/square wave alignment.
14. Startup Power: Defines min/max power for initial startup.
15. PWM Frequency:Sets motor drive frequency.
16. Beep Volume: Adjusts audible alerts.
17. Stopped Brake Level:Braking force when motor is idle (e.g., slope control for crawlers).
18. Sine Startup Range:Throttle range adjustment for smoother crawler starts.
19. Sine Mode Power:Torque adjustment in crawler mode (high values may cause overheating).
20. Running Brake Level: Braking force during motion (prevents rolling in crawlers)
Firmware Upgrade (FLASH Page)
1. Click "Load Firmware"to select the firmware file.
2. Click "Flash Firmware"to upload. - Warning: Do not interrupt power during this process!
1. Low Threshold: Reverse throttle minimum.
2. High Threshold: Neutral stop point.
3. Servo Threshold: Neutral stop point.
4. Servo Dead Band: Neutral dead zone (wider for low-end remotes). Protection Settings
5. Low Voltage Cutoff: Value = protection voltage per cell (e.g., 320 = 3.2V/cell; 2S = 6.4V total).
6. Temperature Limit (°C): ESC reduces power or shuts down if exceeded.
7. Current Limit (Amps): Not recommended for small crawlers.
8. Car/Basher Mode: Practice throttle (first low = brake, second low = reverse). Usually for buggy and TC. Disable for crawlers.
