+# STM8S003
+
+The STM8S003 is almost identical to the STM8S103. The only difference I am
+aware of is the size of the EEPROM: 128 bytes vs. 640 bytes.
+
+I am not sure why the '003 is sold for half the price, or, to put it the
+other way around, why anybody should choose the '103 at all. Did I miss an
+important difference?
+
+All you have to do in order to develop for the STM8S003 is setting the board
+manager for '[Generic STM8S103 breakout board](stm8blue.md)'. Just keep in
+mind not to use EEPROM locations above 127/0x7f.
+
+All differences between the CPUs:

+Feature		| STM8S003	| STM8S103
+------------	| -------------	| ------------
+EEPROM size	| 128 Bytes	| 640 Bytes

+## Known development boards
+
+I am not aware of any dedicated STM8S003 breakout board, but this CPU is
+used in many other low-cost boards:
+
+- [ESP-14](esp14.md) Wifi-Module
+- [W1209](w1209-thermostat.md) Temperature controller
+- HC-12 Wireless serial remote module

+The [stm8ef
+wiki](https://github.com/TG9541/stm8ef/wiki/STM8S-Value-Line-Gadgets) lists
+more.
