FAQ

Q: Should I use STM8S005K6 or STM8S003K3 for a new ESC design?
A: If your ESC will only run standard BLHeli_S (no telemetry extensions, basic PWM), the STM8S003K3 is sufficient and slightly cheaper. If you plan to support Bluejay with bidirectional DShot telemetry, custom startup tones, or extended diagnostic logging, choose the STM8S005K6 — the 32 KB Flash provid

Q: Is the STM8S005K6 pin-compatible with STM8S003K3?
A: Yes, completely. Both use the same LQFP-32 pinout with identical power, ground, reset, SWIM, and VCAP pin assignments. All peripheral alternate-function mappings are identical. You can populate either chip on the same PCB layout — only the BOM line item changes.

Q: Does Bluejay firmware support the STM8S005K6?
A: Yes. Bluejay officially supports all STM8S MCUs with sufficient Flash including the S005. The larger Flash and SRAM are automatically recognized by the firmware's memory configuration. Bluejay compiled for the S005K6 target enables all features (bidirectional DShot, 24–96 kHz variable PWM, startup m

1. Product Overview

The STM8S005K6T6C bridges the gap between the ultra-low-cost S003 (8 KB Flash) and the Performance Line S207 (128 KB Flash). With 32 KB Flash and 2 KB SRAM , it provides quadruple the Flash and double the SRAM of the S003 while retaining the LQFP-32 footprint and pin compatibility. This makes it the ideal upgrade path for drone ESC and BMS designs that have outgrown the S003's memory budget but don't require the cost and complexity of the 128 KB S207. The highlight feature is the 10-channel 10-bit ADC — more than double the S003's 4–5 channels. This enables direct connection of multiple current sensors, voltage dividers, and temperature thermistors without external analog multiplexing, simplifying BOM and PCB layout. For BLHeli_S ESCs running Bluejay firmware at 48–96 kHz PWM, the extra Fl
